Using Advanced Driving Simulator as Design Tool in Road Tunnel Design

Abstract: To obtain more information for tunnel design problems, a virtual model of some proposed tunnel designs was developed to demonstrate the design in advance and to be used as a platform for future tunnel research projects. By combining this model with an advanced driving simulator, the designers can virtually drive through their drawings before construction work is started. In comparison with traditional animation techniques, an interactive virtual model combined with a driving simulator has proved to be useful in many aspects. It is an excellent tool for testing proposed positions of road signs in the tunnel. It is easier to compare alternative sign positions with the three-dimensional virtual tunnel model than with ordinary drawings. Some visual traps not foreseen in the original sign-position design were corrected after detection in the simulator. Traffic engineers reported that they became involved in the tunnel design process at an earlier stage than before, enabling them to work in the final tunnel env...

Tinker: a tool for designing data-centric sensor networks

Abstract: We describe Tinker, a high-level design tool that aids the exploration of the design space in sensor network applications. Tinker is targeted at applications that require real-time assignment of semantic meaning to data, rather than just data storage. Tinker lets users write simple programs, as if they were manipulating individual scalar values, and simulates those computations over continuous streams of sensor data. Tinker does not require (or allow) users to specify details such as routing algorithms or retransmission policies, freeing system designers to rapidly iterate among different broad designs before fleshing out details of the one that looks most promising. We demonstrate Tinker's use in the design and deployment of ElevatorNet, our distributed sensor application that retrofits buildings with per-floor displays of an elevator's position, determined using barometric altimetry.

Raw Shaping Form Finding: Tacit Tangible CAD

Abstract: This paper is aiming at the identification of essential voids in the support of design processes offered by commonly available methods and tools. Some remarkable results were obtained during design sessions with novices and experts by engaging them in tangible experiments that were designed to trigger and enhance their skills, tacit knowing and creativity that enable them to represent their ideas and concepts in an intuitive way. We explored the differences in designer’s behavior during use of “analogue” and digital representation tools. We will explain our laboratory experiments, test results, educational embedding and creative opportunities that emerge from hybrid design tools. Furthermore we propose an exciting hybrid design tool to bring back the tacit and tangible elements of design processing into CAD systems.

Multidisciplinary design optimization with discrete and continuous variables of various uncertainties

Abstract: As a powerful design tool, Reliability Based Multidisciplinary Design Optimization (RBMDO) has received increasing attention to satisfy the requirement for high reliability and safety in complex and coupled systems. In many practical engineering design problems, design variables may consist of both discrete and continuous variables. Moreover, both aleatory and epistemic uncertainties may exist. This paper proposes the formula of RFCDV (Random/Fuzzy Continuous/Discrete Variables) Multidisciplinary Design Optimization (RFCDV-MDO), uncertainty analysis for RFCDV-MDO, and a method of RFCDV-MDO within the framework of Sequential Optimization and Reliability Assessment (RFCDV-MDO-SORA) to solve RFCDV-MDO problems. A mathematical problem and an engineering design problem are used to demonstrate the efficiency of the proposed method.

Computer-aided structural design of punches and dies for progressive die based on functional component

Abstract: Punches and dies are the real operating components and account for a large portion in the progressive die design procedure. This paper presents a structural design tool for punches and dies for progressive dies of motor core based on functional component. The descriptive model of punch and die component is established which contains three aspect of information, geometry information, assembly-related constraint attribute and hole-related information on plates. Based on the classification and 3D modeling method of punches and dies, the library of components for punches and dies is set up according to the descriptive model. Methods for modeling and data management for components of punches and dies are discussed in detail. The proposed tool for progressive die for motor cores can complete the design of five classes of punches and dies and generate holes on plates automatically. This design tool is constructed on a PC and integrated with a SolidWorks CAD system. The progressive die design for the motor core of house appliance is employed as a practical example to demonstrate the effectiveness of the design tool. The results reveal that it can dramatically improve the design quality and can save both time and costs.
