Design, Analysis and Optimization of Four Stroke S.I. Engine Piston using Finite Element Analysis in ANSYS software

Abstract

The aim of this paper is to design, analysis and optimization of four stroke S.I. engine piston, which is strong
and lightweight using finite element analysis with the help of ANSYS Software. Solid Model of piston has been made using
ANSYS 16.2 Geometric module and Thermo-Mechanical (Static Structural Analysis + Steady-State Thermal Analysis)
analysis is done to analyze stresses, total deformation and factor of safety distribution in various parts of the piston to
know the effect due to gas pressure and thermal variations using ANSYS 16.2.
Piston optimized using Response Surface Optimization module. The thickness of piston barrel is reduced by
52.28%, the thickness of the piston crown head increased by 9.41%, the width of top land increased by 3.81%, axial
thickness of the ring is increased by 2.38% and radial thickness of the ring reduced by 5.31%, resultant mass of the piston
reduced by 26.07% and it’s factor of safety increased by 3.072%.
