Stress Optimization of S.I. Engine Piston

Rahul D. Raut ^[2] | Satish Mishra

Abstract: The performance of any automobile largely depends on its size and working in dynamic conditions. The piston is a heart of the engine and its working condition is the worst one of the key parts of the engine in the working environment. The good design of the piston optimization can lead to a mass reduction on the base of stress analysis satisfying the requirements of automobile specifications with cost and size effectiveness. Piston is the part of engine which converts heat and pressure energy liberated by fuel combustion into mechanical works. Engine piston is the most complex among automotive. This paper work describes stress optimization of Piston for I. C. Engine. The stress distribution of piston by using FEM to be investigate and analyze. The stresses due to combustion are considered to avoid the failure of the piston. Intensity of structural stresses should be reduced to have safe allowable limits. This paper introduces an analytical study of the structural effects on the piston head. CAD software Creo is used to model the piston and stress optimisation is performed by using Creo-Simulate. The paper describes the piston optimization with using finite element analysis technique to predict the higher stress and critical region on the component. The optimization is carried out to reduce the stress concentration on the head of the piston.
