Finite Element Simulation of Engine Piston and Subsystem

Abstract

This paper presents a comprehensive study on the structural and thermal analysis of pistons used in internal combustion engines. The study uses finite element analysis (FEA) and ANSYS software to evaluate mechanical and thermal stress distributions in engine conditions. It emphasizes the importance of piston geometry optimization, material selection, and coatings for improved efficiency, reduced emissions, and durability. This research discusses the use of transient structural and thermal analysis to determine structural deformation, stress, and strain in piston and piston rings under various temperature and loading conditions. Transient structural analysis examines how the piston and piston ring's structure changes over time due to dynamic forces, such as pressure variations and mechanical loads. It helps predict deformation, bend, or break under different operating conditions, identifying potential weak points or areas of high stress concentration. Also modified geometry taken for piston to analysed and identify better suited crown geometry for better performance.
