Design and analysis of piston using aluminum alloy and composites in Solidworks and Ansys

Abstract

The present paper reports the modelling and analysis of piston fabricated from Steel, Aluminum alloy and Composites for 4-stroke petrol engine of a specific version followed by comparison between the both. Solidworks software is used for 3D modelling of the piston. Ansys software is used for static structural and steady state thermal analysis of the piston. A static-structural analysis is being performed to find out the deformation, stresses, strains, and forces in structures or factors caused by the loads. A static analysis calculates the impact of steady loading conditions on a structure, while ignoring inertia and damping as those carried by time varying loads. Steady state thermal analysis is used for evaluating the thermal equilibrium of a system in which the temperature remains constant over time. Steady-state thermal analysis can be used to determine the temperature distributions in an object with thermal loads that do not vary with time. The heat transfer includes conduction, convection and radiation. Most thermal analyses are steady state thermal analyses. Total Deformation, Factor of Safety (F.O.S.), Equivalent (Von-mises) stress and Equivalent (Von-mises) strain were obtained under static structural analysis for piston using different materials. Total heat flux, Directional heat flux and temperature distribution were obtained using steady state thermal analysis. Performance of standard material used for piston and aluminum alloys was compared and the best material was recommended for manufacturing of piston.
