Design Analysis and Optimization of I.C. Engine Piston Using Finite ElementAnalysis (Ansys)

Abstract

In I.C. Engine, piston is most complex and imperative part consequently for smooth running of vehicle pistonshould be in proper working condition. Pistons fail mainly due to mechanical stresses and thermal stresses. Analysisof piston is done with boundary conditions, which includes pressure on piston head during working condition anduneven temperature distribution from piston head to skirt.The main purposes isto examine and analyze the thermal stress and maximum orminimum principal stresses, Vanishes stresses distribution onengine piston at the real engine condition during combustionprocess. The paper describes the optimization techniques withusing finite element analysis technique (FEM) to predict thehigher stress and critical region on that component. The stressconcentration on the piston head, piston skirt and sleeve arereduces by optimization with using computer aided design, ProENGINEER/ CREO software the structural model of a pistonwill be developed.
