Design and analysis of connecting rod using composite materials (AL7075, AL6061, AL7075+SiC, AL6061+SiC)

Abstract

Abstract Connecting rod is a vital part of an internal combustion engine which forms a link between piston and the crankshaft. Due to huge amount of forces acting on the piston owing to high engine load and rpm, cyclic compressive and tensile forces act on the connecting rod and results in fatigue and failure. So, to in order avoid this, the existing connecting rod is to be replaced by composite materials. Because these materials have good mechanical properties such as wear resistance, hardness and high tensile strength. A 3D model of connecting rod is modeled using Solidworks and FEA analysis is carried out by ANSYS 18.2. In this paper analysis is performed on the connecting rod using AL7075, AL6061, AL7075+10%SiC and AL6061+10%SiC to find out the best material for construction of connecting rod.
