Design and Analysis of Connecting Rod Using Different Materials

Abstract

Abstract: Connecting rod is an important component in an engine. Connecting rod used to connect between piston and crankshaft. The purpose of the project was to analysis connecting rod fracture using Finite Element Analysis. The stress and thermal for connecting rod can analyzed with this software. With this software, can analysis the stress and thermal for connecting rod. Before that, draw the connecting rod using CATIA V5 W/F software, then exported to the finite element analysis (ANASYS software). This project focused on analysis. Overall, this project will acquire the analysis of fracture connecting rod. The connecting rod is under tremendous stress from the reciprocating load represented by the piston, actually stretching and being compressed with every rotation, and the load increases to the third power with increasing engine speed. Failure of a connecting rod, usually called „throwing a rod‟ is one of the most common causes of catastrophic engine failure in cars, frequently putting the broken rod through the side of the crankcase and thereby rendering the engine irreparable; it can result from fatigue near a physical defect in the rod, lubrication failure in a bearing due to faulty maintenance, or from failure of the rod bolts from a defect, improper tightening, or re-use of already used (stressed) bolts where not recommended . Connecting rod produced from alloy steel forging or aluminium alloy were used to a limited extend in early practice, the primary object being to reduce the loading on the big end and main bearing. Connecting rods used these days are the result of advancements in metallurgy and machining techniques. These rods are the critical part of an engine because even a small defect in it can lead to catastrophic engine failure in automobiles. Most of the automobile manufacturers are engaged in making superior and high performance connecting rods at economical process
