DESIGN AND ANALYSIS OF CONNECTING ROD

Abstract

The connecting rod is an important part of an I.C. engine. It has to carry the thrust force from piston to the crank shaft. The connecting rod is subjected to high degree of stresses. The main objective of the paper is to replace the conventional material used for connecting rod with a new composite material to reduce its weight. This paper deals with the design of a connecting rod for Hero Splendor vehicle using aluminium fly ash silicon composite. The model of the connecting rod is developed using a modeling software. The static analysis of the designed connecting rod is done using FEM software and the results are compared with the existing material   C70 steel. Further a wear test is carried out to check the wear characteristics of the new composite material and compare it with the existing material. By using aluminium fly ash silicon composite weight reduction of the connecting rod is achieved. The designed connecting rod is having higher stiffness to weight ratio than the existing connecting rod.
