Abstract:

Connecting rod is a critical component used in internal combustion engine. It is subjected to different types of loading conditions like gas pressure, inertia loads, and frictional forces. It must be sufficiently strong, right and light in weight. In this paper, a connecting rod used in single cylinder four stroke petrol engines has been designed and developed using Pro-E wildfire 4.0. Forged steel material has been used which has high reliability and longer life due to high endurance limit. The design is based on load considering 5N/ mm2. Structural system of connecting rod has been analyzed using finite element techniques. Finite element analysis has been done to determine the Von Mises stresses in the model of connecting rod for given loading conditions. It was observed that Von Mises stress at big end shoulder is critical. That has been solved by changing the radius of curvature and considerable weight reduction has been achieved by changing the material.
