TL;DR: This work proposes the use of the embedded electrical current signals of the control unit (MCSA) as an approach to detect and diagnose mechanical faults using the discrete wavelet transform (DWT) to analyze the electric motor current signals in the time-frequency domain.
Abstract: In prognostics and health management (PHM), the majority of fault detection and diagnosis is performed by adopting segregated methodology, where electrical faults are detected using motor current signature analysis (MCSA), while mechanical faults are detected using vibration, acoustic emission, or ferrography analysis. This leads to more complicated methods for overall fault detection and diagnosis. Additionally, the involvement of several types of data makes system management difficult, thus increasing computational cost in real-time. Aiming to resolve that, this work proposes the use of the embedded electrical current signals of the control unit (MCSA) as an approach to detect and diagnose mechanical faults. The proposed fault detection and diagnosis method use the discrete wavelet transform (DWT) to analyze the electric motor current signals in the time-frequency domain. The technique decomposes current signals into wavelets, and extracts distinguishing features to perform machine learning (ML) based classification. To achieve an acceptable level of classification accuracy for ML-based classifiers, this work extends to presenting a methodology to extract, select, and infuse several types of features from the decomposed wavelets of the original current signals, based on wavelet characteristics and statistical analysis. The mechanical faults under study are related to the rotate vector (RV) reducer mechanically coupled to electric motors of the industrial robot Hyundai Robot YS080 developed by Hyundai Robotics Co. The proposed approach was implemented in real-time and showed satisfying results in fault detection and diagnosis for the RV reducer, with a classification accuracy of 96.7%.

TL;DR: In this paper, an oil-soluble viscosity reducer was used to decrease the viscosities of heavy oil by decreasing the asphaltene concentration and the size of the aggregations in the extraheavy oil.
Abstract: In this paper, extraheavy oil recovery assisted by CO2 and an oil-soluble viscosity reducer under deep reservoir conditions was experimentally investigated. Specifically, the viscosity reduction efficiency of the oil-soluble viscosity reducer was measured, and the morphological characteristics of the asphaltenes in the heavy oil were observed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). CO2 huff-n-puff experiments were carried out to determine the oil recovery factor and the oil/gas exchange ratio. The properties of the produced oil were tested, and the oil saturation in cores was scanned through nuclear magnetic resonance (NMR). The experimental results show that the oil-soluble viscosity reducer decreases the viscosity of extraheavy oil by decreasing the asphaltene concentration and the size of the asphaltene aggregations in the extraheavy oil. CO2 huff-n-puff assisted by an oil-soluble viscosity reducer can considerably improve the oil recovery of extraheavy oil. When the concentration of the viscosity reducer increases from 0 to 10 wt%, the oil recovery factor after five cycles increases from 18.74 % to 34.44 %, and the foamy oil effect is stimulated. An economic concentration range of 1–3 wt% is suggested for field CO2 huff-n-puff applications. With increasing CO2 huff-n-puff cycles, the cyclic oil recovery factor and oil/gas exchange ratio sharply decrease. The oil recovery and oil/gas exchange ratio of the first two cycles are considerably higher than those of the last three cycles. The oil saturation tested by NMR shows that the sweep area of CO2 huff-n-puff is limited to the first two-thirds of the core, indicating that the injection volume of CO2 should be increased with each successive cycle, and the well distance should be suitably decreased to improve the oil recovery of the whole reservoir.

TL;DR: In this article, an elastic transmission error compensation method for a rotary vector (RV) speed reducer is proposed to improve its transmission accuracy based on error sensitivity analysis, which can be compensated by tooth surface modification of cycloidal gears.
Abstract: An elastic transmission error (TE) compensation method for a rotary vector (RV) speed reducer is proposed to improve its transmission accuracy based on error sensitivity analysis. Elastic and geometric TEs of the RV speed reducer can be compensated by tooth surface modification of cycloidal gears. Error coefficients of the TE of the RV speed reducer are derived to determine error factors with positive effects on TEs based on error sensitivity analysis. A total TE, including the elastic TE, is obtained by using Adams. The elastic TE compensation method is developed to calculate modification values of error factors with positive effects on the TE to decrease the elastic TE of the RV speed reducer. TE simulation results show that the elastic TE accounts for 25.28% of the total TE, and calculation results show that the maximum contact force and normal deformation of the modified prototype are obviously improved. The feasibility and accuracy of the proposed elastic TE compensation method for RV speed reducers were verified by TE experiments. TE experiment results showed that the TE of the modified RV speed reducer is 47.22% less than that of the initial RV speed reducer.

TL;DR: A high-efficiency compact cycloidal reducer for legged robots that uses needle roller bearings in all parts where contact occurs during the power transfer process inside the reducer, which greatly improves the efficiency compared to a cycloid reducer using free rollers.
Abstract: Actuating systems for the proprioceptive control of legged robots must have a high mechanical efficiency and mechanical bandwidth for high torque transmission to avoid power transmission losses. We developed a high-efficiency compact cycloidal reducer for legged robots that uses needle roller bearings in all parts where contact occurs during the power transfer process inside the reducer, which greatly improves the efficiency compared to a cycloidal reducer using free rollers. We also proposed a subcarrier structure that distributes the load and allows the cycloidal reducer to respond robustly to impacts that may occur during the locomotion of the legged robot. The subcarrier increases the stiffness, which improves the mechanical bandwidth. A cycloidal reducer was manufactured with > 90% efficiency in most operating ranges; it weighs 766 g and can withstand a torque of more than 155 Nm. The cycloidal reducer module coupled with the motor indicated a torque control bandwidth of 72 Hz, so it can be used for legged robots with agile motions.

TL;DR: It is proposed to replace the gearbox with rigid mechanical connections with a double planetary gear reducer and, thereby, ensure the operation of the electric drive with two independent mechanical channels and implements the indicated operating modes at a reduced speed, avoiding expensive downtime.
Abstract: The operation of a drilling rig top drive system (TDS) in drilling practice at a great depth or during the construction of a drill pipe stand in the case of failure of one of two motors is considered. In the existing kinematic scheme of most domestic and foreign TDSs, the two motors are mechanically rigidly connected to the drive shaft through a gear reduction unit. It is proposed to replace the gearbox with rigid mechanical connections with a double planetary gear reducer and, thereby, ensure the operation of the electric drive with two independent mechanical channels. Such a kinematic scheme with independent mechanical channels makes it possible to provide the drilling rig operation at great depths in the case of failure of one of the drives and when constructing pipes when disassembling the drilling string. Due to a wider range of torque control for each of the two channels, in the case of failure of one of the drives, the proposed scheme implements the indicated operating modes at a reduced speed, avoiding expensive downtime. The static mechanical characteristics of the TDS for the existing and proposed systems are presented. The calculation of the mechanical converter providing the required gear ratios for each of the mechanical channels is performed. The operation of the control system and power distribution unit of two drives is considered.

TL;DR: In this article, a universal static analysis model was developed to calculate the ball load distribution of flexible bearing in harmonic reducers, and the validity of the proposed model was proved by studying two types of flexible bearings mounted on an elliptical cam and a four-force action-type cam.
Abstract:
Harmonic reducers are generally supported by flexible bearings. The elastic deformation of the flexible bearing enables the harmonic reducer to satisfy high reduction ratio performance. By considering the flexible outer ring and noncircular inner ring of the flexible bearing, a universal static analysis model was developed to calculate the ball load distribution of flexible bearings in harmonic reducers. The validity of the proposed model was proved by studying two types of flexible bearings mounted on an elliptical cam and a four-force action-type cam, respectively. Several results validate the use of the model to assess the ball load distribution instead of a more time-consuming finite element method. Influences of design parameters in the flexible bearing on the load distribution were investigated, which makes reference for the optimal design of the flexible bearing.

TL;DR: It is shown that through selected tolerance control on the machine parts, the accuracy of the gear drive can be retained and can be useful for controlling the manufacturing precision on themachine parts and assessing the overall accuracy ofThe mechanism in the design phase.
Abstract: The rotor vector (RV) gear reducer is a mechanism used for motion and torque transmission. With characteristics similar to a traditional cycloidal gear drive, it has been popularly applied in precision machinery because of its high-speed reduction ratio, large torque capacity, and high efficiency. In this work, we aim to analyze the kinematic error (transmission error) of the RV reducer with manufacturing and/or assembly tolerances. Formulae for the kinematic error are established by using the theory of gearing as well as tooth contact analysis. Subsequently, sensitivities of the kinematic error with respect to various design parameters are investigated. Lastly, a process to simulate the distribution of maximum kinematic errors of the gear reducer with various tolerance grades of the parts is developed via Monte Carlo method. It is shown that through selected tolerance control on the machine parts, the accuracy of the gear drive can be retained. The results of this work can be useful for controlling the manufacturing precision on the machine parts and assessing the overall accuracy of the mechanism in the design phase.

TL;DR: Two novel methods are proposed to estimate torque of robotic joint with harmonic reducer via calibration of its existing flexibility without the need for any additional elastic elements, using a new harmonic drive compliance model and a back-propagation neural network.
Abstract: Joint torque sensing is an important technique for high-performance control of modern robotic systems, especially in an environment that requires man-machine collaboration. However, in many cases, traditional torque sensors are not suitable for robots because of the inevitable increase of joint flexibility and joint size. To address this problem, two novel methods are proposed to estimate torque of robotic joint with harmonic reducer via calibration of its existing flexibility without the need for any additional elastic elements. The first approach utilizes a new harmonic drive compliance model, which is more convenient for calibration and less dependent on the manufacturer’s parameters to estimate the output torque. The second method relies on a system based on a back-propagation (BP) neural network to fit the non-linear relationship among the output torque, motor current, and other information that can be obtained from double encoders mounted on motor-side and load-side. The two proposed methods were experimentally investigated and the results show that the estimated torque values were in good agreement with the measurements obtained using a commercial torque sensor. Finally, different suitable application scenarios are presented according to the specific performance of each technique.

TL;DR: A novel method for simultaneous estimation of unknown switched external disturbance and precise position control of dynamical systems which employ worm gear drive reducers is proposed and improvements resulted from incorporation of friction estimation algorithm are analyzed.
Abstract: This paper proposes a novel method for simultaneous estimation of unknown switched external disturbance and precise position control of dynamical systems which employ worm gear drive reducers. This algorithm is based on an improved discrete sliding mode control (DSMC) design which ensures convergence to the desired sliding set without introducing chattering effects to the dynamical system. In order to improve the performance of DSMC and to obtain an accurate estimation of gearbox model, a new method for incorporation of switched friction is proposed in the presence of external disturbance. To this end, the dynamical response of worm gear drive reducer is investigated in distinct switched disturbance modes of resistive disturbances, assistive disturbances and no disturbance to obtain approximate functions describing system dynamics in aforementioned configurations. In comparison with the feedback data, the obtained models permit appropriate incorporation of friction into the improved DSMC scheme. Based on multiple common Lyapunov functions and calculation of virtual reference signals for armature currents, the feasibility of control algorithm is ensured in all modes of switched dynamics. The effectiveness of the proposed estimation and control schemes has been verified using an experimental setup employing a worm gear drive reducer on which multiple permanent magnet DC motors are installed, and improvements resulted from incorporation of friction estimation algorithm are analyzed.
TL;DR: Cutting the number of reducers and revising the clustering helped reducers to perform their jobs almost simultaneously and improve the execution time by about 3.9% less than the fastest algorithm.
Abstract: MapReduce is used within the Hadoop framework, which handles two important tasks: mapping and reducing. Data clustering in mappers and reducers can decrease the execution time, as similar data can be assigned to the same reducer with one key. Our proposed method decreases the overall execution time by clustering and lowering the number of reducers. Our proposed algorithm is composed of five phases. In the first phase, data are stored in the Hadoop structure. In the second phase, we cluster data using the MR-DBSCAN-KD method in order to determine all of the outliers and clusters. Then, the outliers are assigned to the existing clusters using the futuristic greedy method. At the end of the second phase, similar clusters are merged together. In the third phase, clusters are assigned to the reducers. Note that fewer reducers are required for this task by applying approximated load balancing between the reducers. In the fourth phase, the reducers execute their jobs in each cluster. Eventually, in the final phase, reducers return the output. Decreasing the number of reducers and revising the clustering helped reducers to perform their jobs almost simultaneously. Our research results indicate that the proposed algorithm improves the execution time by about 3.9% less than the fastest algorithm in our experiments.

TL;DR: It is proven by experiments that the performance data of the harmonic reducer in space work can be more accurately obtained by using the test system mentioned in this paper, which is convenient for further research on related lubricating materials.
Abstract: The harmonic reducer, with its advantages of high precision, low noise, light weight, and high speed ratio, has been widely used in aerospace solar wing deployment mechanisms, antenna pointing mechanisms, robot joints, and other precision transmission fields. Accurately predicting the performance of the harmonic reducer under various application conditions is of great significance to the high reliability and long life of the harmonic reducer. In this paper, a set of automatic harmonic reducer performance test systems is designed. By using the CANOpen bus interface to control the servo motor as the drive motor, through accurately controlling the motor speed and rotation angle, collecting the angle, torque, and current in real time, the life cycle test of space harmonic reducer was carried out in high vacuum and low temperature environment on the ground. Then, the collected data were automatically analyzed and calculated. The test data of the transmission accuracy, backlash, and transmission efficiency of the space harmonic reducer were obtained. It is proven by experiments that the performance data of the harmonic reducer in space work can be more accurately obtained by using the test system mentioned in this paper, which is convenient for further research on related lubricating materials.
TL;DR: A performance margin modeling and reliability analysis for harmonic reducer considering multi-source uncertainties and wear and the results show that the proposed method can provide some suggestions to the design and manufacturing phases of the harmonic reducers.
Abstract: The harmonic reducer of the space drive mechanism is one of the critical components of the satellite remote sensing system and its reliability is always required strictly in practice. During the manufacturing and usage processes of the harmonic reducer, uncertainties are ubiquitous and performance degradation is inevitable, which is mainly caused by the wear between the meshed tooth surfaces. They influence the reliability of harmonic reducer. In this paper, a performance margin modeling and reliability analysis for harmonic reducer considering multi-source uncertainties and wear is proposed. Firstly, based on the functional principle and the influence of wear, the performance margin model is established using hysteresis and transmission errors as key performance parameters. Then multi-source uncertainties are analyzed and quantified, including manufacturing errors, uncertainties in operational and environmental conditions, and uncertainties in performance thresholds. Finally, the reliability model is constructed based on the performance margin. A case study of a harmonic reducer is applied and the reliability sensitivity analysis is implemented to show the practicability of the proposed method. The results show that the proposed method can provide some suggestions to the design and manufacturing phases of the harmonic reducer.

TL;DR: In this article, a power drive system with a field regulated synchronous reluctance motor on a KhPT-250 cold rolling mill is presented, which is used to increase the mill output by 10 to 15% with the quality of rolled products improving by 20 to 25%.
Abstract: This article is devoted to development of synthesis of power drive system of KhPT-250 cold rolling mill. Selection procedures for process variables of the reducer, electric machine, and power circuits have been developed. It has been noted that the configuration of power circuits can decrease failures by about 30%. It has been demonstrated that, in the power drives of the KhPT-250 mill, it is required to take pipe deformability into account and the control object should be considered as a multicircuit double-mass system. It is proposed to select the gear reduction rate on the basis of the criterion of minimum oscillation. With this aim in mind, the methods of frequency synthesis have been applied to construct asymptotic frequency characteristics used for determination of the reducing gear factor in the case of a restricted amplitude of the resonance maximum. Using the finite element method, the geometrical parameters of the stator and rotor of a synchronous reluctance machine have been selected, and its weight and dimensions have been improved by about 35%. Predictions demonstrate that the best ratio of the flow longitudinal constituent to the transversal constituent is obtained for a axially laminated rotor. Implementation of a power drive system with a field regulated synchronous reluctance motor on a KhPT-250 cold rolling mill made it possible to increase the mill output by 10–15%, with the quality of rolled products improving by 20–25%. According to preliminary estimations, the annual efficiency of the power drive system will be from 2 to 5 million rubles.
TL;DR: A simplified cycloidal mechanism (CM) is constructed to fulfill dynamic analysis and reliability evaluation, and its dynamic forces and failure characteristics using finite element methods (FEM).
Abstract: This paper reported the designed approaches of cycloidal mechanisms, studied its dynamic forces and failure characteristics using finite element methods (FEM). A simplified cycloidal mechanism (CM) is constructed to fulfill dynamic analysis and reliability evaluation. The studied results show that the loads of the mechanism are shared mainly by a half of the outer rollers and the inner pins. The possible failures of the mechanism will occur at the inner pins caused by the bending stress, and at the cycloid disc induced by the contacting stress. The failure of the inner pins will dominate the damage of the mechanism. A method of evaluating stress variation is proposed for fulfilling reliability design. The stress variations are derived according to the data in dynamic analysis by regression analysis. The methods of design modification are reported for improve the reliabilities. The allowable loads of the CM can be decided accordingly based on the analyzed information.

TL;DR: In this paper, a cylindrical and disk structure was designed to improve structural stiffness, ensure regular deformation patterns, and minimise the angular errors caused by weak stiffness supports in the conventional instrument.
Abstract: High precision reducer is the core component of industrial robot. Its performance test is the key to improve product quality and ensure the accuracy of robot operation. One of the basic geometric parameters in performance test is the angle, which refers to the angular displacement of the input or output of the tested reducer. Based on a vertical instrument, angular measurement systems are designed in this article. In order to ensure the precision of results, the angle encoder is as close as possible to the measured object, which shortens the measurement chain and reduces the number of error sources. A cylindrical and disk structure improves the structural stiffness, ensures regular deformation patterns, and minimizes the angular errors caused by weak stiffness supports in the conventional instrument. Another system consisting of an autocollimator and a regular polyhedron, whose output is taken as angular standard, calibrates absolute circular gratings in the instrument. The model based on back propagation neural network can compensate the errors over the whole circumference, and finally get the angular displacement of input and output of the tested reducer in the drive process accurately. After compensation, the angular measurement errors of the instrument are within ±2 arc seconds.

TL;DR: The adopted technique included noise-canceling technique, synchronous temporal mean (TSA), and continuous Morlet wavelet transform (CWT), designed to extract resources and diagnose local gear damage.
Abstract: In predictive maintenance, vibration signal analyses are frequently used to diagnose reducer failures because these analyses contain information about the conditions of the mechanical components. Reducer vibration signals are very noisy and the signal-to-noise ratio is so low that extracting information from the signal components is complex, especially in practical situations. Therefore, signal processing techniques are used to solve this problem and facilitate the retrieval of information. In this work, the adopted technique included noise-canceling technique, synchronous temporal mean (TSA), and continuous Morlet wavelet transform (CWT), designed to extract resources and diagnose local gear damage. These techniques are used in measured signals in an experimental workbench consisting of the gear pair coupled to a motor and a generator. The experiment was monitored according to the conditions of a gear pair throughout its useful life. The continuous wavelet transforms accurately identified faults in the gear teeth, and it was possible to detect in which tooth the fault was occurring.
