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.
