ANALYSIS OF FATIGUE FAILURE OF CONNECTING ROD USED IN A LIGHT COMMERCIAL VEHICLE (LCV) THROUGH FEA

The main objective of this study was to investigate the design,mass and cost reduction of connecting rod made up of structural steel for 970 cc four cylinder four stroke engines . Every stroke of the engine subjected to its adjacent components to cyclic loading that pulls and pushes the connecting rod and crankshaft. The design of the Connecting rod can be done in a justifiable manner if an attempt is made to identify the effects of the operating loads on the component in the form of the type of stress induced with its peak value and the location of these stresses over the component. This study consists of two major sections,Finite Element Analysis and Optimization for design and mass reduction. In this paper,existing connecting rod is been optimized with change of various design parameters for I - Section followed by 3- D CAD- modeling using Solid Works. Second order Tetrahedron mesh is been carried out in Hypermesh. 3 -D finite element analysis is planned to be carried out by virtue of static stress analysis and followed by fatigue life prediction of Connecting rod using Ansys Workbench. Alternatives for Design would be suggested while attempting to modify the geometry of the Connecting rod by changing the different parameters. https://www.ijiert.org/paper-details?paper_id=14075
