Abstract: A piston is a reciprocating component of an engine which is used to convert the chemical energy obtained by the combustion of fuel into mechanical power. The purpose of the piston is to transfer the energy to crankshaft via connecting rod. The main objective of this work is to design and analyse the stress distribution and perform structural analysis on the piston and determine the factor of safety of the piston for various materials. Design of the piston is carried out using Creo Parametric 5.0 software. Structural analysis is performed using ANSYS on four different materials and the factor of safety for each material is determined. Failure of piston occurs due to various thermal and mechanical stresses. Hence by determining the factor of safety of the materials, the material with the highest factor of safety is used to improve the efficiency and life span of piston.

Keywords: Factor of safety, Creo parametric 5.0, ANSYS, structural analysis.
