In this study, structural analysis is investigated on conventional piston made of Al alloy A2618. Secondly analysis are performed on piston made of Al-GHY1250 and Al-GHS1300.The material used for the design of piston should have light weight, low cost, structurally and thermally withstand at very high pressure and temperature condition that will occur in combustion process. In this project, it has been decided to study a particular piston design and its capability for maximum gas pressure. In this work, initial planning is to make piston model using solid modeling software Creo / Pro 5.0. It has been decided to mesh the geometry analyze using ANSYS. For the analysis of piston input conditions and process of analysis, a lot of literature survey has been done. High combustion gas pressures will act as a mechanical loads and causes major stresses in the critical region of the piston. Detailed static structural analysis is carried out for various loading conditions like maximum gas pressure load. Comparative study is done to select best material.
