Abstract: The aim of this work is to analyze various failure modes occurred in crankshaft of Briquette machine subjected to cyclic loads and also to improve the overall design of the crankshaft. Finite Element Analysis provides variety range of solution in engineering industries. One among them is the analysis of Briquette machine - crank shaft. The real world problem going to solve state-of-art technology called FEA. Briquette machine used to compress the agricultural waste into high calorific solid fuel. When small particles of solid materials are pressed together to form coherent shapes of larger size, the process are termed briquette. Power from motor is used to rotate the flywheel. Crank shaft, connecting rod & Piston assembly converts the rotary motion into linear motion. Crank shaft is one of the major component plays important role of the operation of the machine. FEA used for validation, design improvement, fatigue life cycle calculation, and optimization of crank shaft. ANSYS finite element code used to solve the problem. This work investigates the fatigue analysis for various failure modes occurring in the briquette machine. 3D model of crankshaft as per the existing dimensions are created and the model is imported in FEA software. The driving force of the reciprocating members, vector and acceleration analysis are calculated by using analytical method. The parameters such as material properties, boundary conditions, mechanical properties, and load on reciprocating members are given as an input and results obtained from Ansys workbench software are analyzed at various failure modes. Finally, weak areas of failure are identified and corrected.

Abstract: Crankshaft is one of the most critical components for effective and precise working of the internal combustion engine. In this paper, a static structural and dynamic analysis was conducted on a single cylinder four-stroke diesel engine crankshaft. A solid model of the crankshaft was created using higher-end computer-aided design software, i.e., Pro/Engineer software according to the dimensional details drawing of the existing crankshaft. Finite element analysis was performed using ANSYS software under the static and dynamic condition to obtain the variation of stresses at different critical locations of the crankshaft. Boundary conditions were applied on finite element model in accordance with engine specification chart and engine mounting conditions. Optimization of the crankshaft was studied in the area of geometry and shape on the existing crankshaft; however especially working on geometry and shape optimization, the optimized crankshaft design should be replaced with existing crankshaft, without changes in the engine block and cylinder head. The optimized crankshaft helps to improve the performance of the engine and causes reduction in weight. This optimization study of the crankshaft helps to reduce 4.37% of the weight in the original crankshaft.

TL;DR: This paper provides the information regarding the metal jobs failure which was detected earlier by using fuzzy logic and these parameters used in labVIEW for designing fuzzy logic inferential system.
Abstract: Metal jobs (connecting rods) are the one of the essential components of engine's design and also used in industry purpose. The Metal jobs must be able to withstand heavy loads and transmit a great deal of power, the failure of metal jobs leads to damaging engine and other equipment's. This paper provides the information regarding the metal jobs failure which was detected earlier by using fuzzy logic. The failure of metal jobs were predicted by applying different amount of tension on metal jobs which are made of different type of metals like aluminium, copper, steel etc. These different types of metal jobs have a different tensile strength and elongation property, if the applied tension is greater than tensile strength of the material then the metal jobs will break's. So here the tensile strength of the metal jobs were predicted earlier and this values were stored in database. Prediction of failure analysis is done with the help of Hall sensor (AH49E TO-92S) which will get the elongation parameter changes and these parameters used in labVIEW for designing fuzzy logic inferential system. This fuzzy logic will helpful for diagnosing and analysis. In this analysis the tension input values are given to labVIEW to know the break point of the metal jobs without testing. It will give the indication when the metal job is abort to break.

Abstract: The stress analysis and modal analysis of a 4-cylinder crankshaft are discussed using finite element method in this paper. Three-dimension models of 480 diesel engine crankshaft and crankthrow were created using Pro/ENGINEER software The finite element analysis (FEM) software ANSYS was used to analyse the vibration modal and the distortion and stress status of the crankthrow.The maximum deformation, maximum stress point and dangerous areas are found by the stress analysis of crankthrow. The relationship between the frequency and the vibration modal is explained by the modal analysis of crankshaft. The results would provide a valuable theoretical foundation for the optimization and improvement of engine design. Index Terms—finete element analysis; modal analysis; strss analysis; crankshaft

The effective material and geometrical properties are measured, and the dynamic behavior is investigated through impact testing. The three-dimensional finite element models are constructed and an analytical modal analysis is thenperformed to generate natural frequencies and mode shapes in the three-orthogonal directions. The finite element modelagrees well with the experimental tests and can serve as a baseline model of the crankshaft.
