ANALYSIS OF STRESSES INDUCED IN CONNECTING ROD OF TWO WHEELER ENGINE

Design Engineering

An automobile engine connecting rod is a high volume production and critical component. Connecting rod is the connecting link between the piston and the crank. And transmit the push and pull from the piston pin to crank pin, therefore converting the reciprocating motion into the rotary motion of the crank. Basically connecting rods are manufactured using carbon steel and recently aluminum alloys are finding its application in connecting rod. In automobile engines, the connecting rod is subjected to cyclic loads. These are seen by high compressive loads due to combustion, and high tensile loads due to the connecting rod mass of inertia. The main objective of this project is the weight optimization of a connecting rod in an automobile engine. To get the idea about designing the connecting rod, various stress to be considered. While going across through design, the connecting rod may be tried by various materials and comparing the result of all materials. Finite Element Method (FEM) is useful for the modeling and analysis of connecting rod. The present work has been established to replace the existing connecting rod made of forged steel with the aluminum MMC connecting rod for weight optimization.
