Design and Optimization of piston using finite element analysis

This work describes the stress distribution of the piston by using finite element method (FEM). FEM is performed by using computer aided engineering (CAE) software. The main objective of this project is to investigate and analyze the stress distribution of piston at the actual engine condition during combustion process. The parameter used for the simulation is operating gas pressure and material properties of piston. The report describes the mesh optimization by using FEM technique to predict the higher stress and critical region on the component. Aluminium is selected as piston material. It is important to locate the critical area of concentrated stress for appropriate modification. Computer aided design (CAD) software Catia is used to model the piston, and analysis is performed by using ANSYS.
