Weight optimization of Piston using CREO parametric and ANSYS

Abstract

The Piston is a crucial element of an I.C engine. The Piston is a reciprocating component of the I.C engine that converts thermal energy and pressure energy liberated by the ignition of the air-fuel into mechanical work. The design of the Piston and selection of material is a challenging assignment for the designer. This paper describes the design procedure for a piston of a four-stroke petrol engine. The optimization of Piston with different materials was carried out in the present work. The analysis is done by considering two designs, one is primary, and the other is an optimized one. The modelling is achieved by utilizing the Creo parametric and further investigation in ANSYS workbench. The design process involves the evaluation of varied piston measurements using the analytical technique at the maximum power condition. While computing various aspects, the cumulative impact of mechanical stress and thermal distribution are considered. Three different materials are considered for designing the Piston, and their performances are scrutinized. The Aluminium cast alloy is the most used in manufacturing the pistons. However, the analysis done in this project has given better results for Aluminium Silicon Carbide. All the results for it have turned out to be better than the Aluminum Cast alloy.
