Design Evolution of a Diesel Engine Piston

Abstract

A piston is a major component of to and fro motion engines. It transfers the power form expanding gases in the cylinder to the crank shaft through the con rod. Now a three dimensional solid model of piston along with different dimensions is designed with the help of AutoCAD software. By applying the same pressures and temperatures for different Piston head diameter with the help of AutoCAD and Ansys 16.0 Software, we can get the evaluated results of von-misses stresses, thermal flux, and thermal gradient and directional deformations for that piston design. General materials for the piston is Structural steel, cast steel, forged steel, Aluminum alloys, and Nickel alloys. In our project Cast Aluminum alloy is used as piston material. It is an excellent material in thermal conductivity and also light in weight. The stress analysis results also help us to improve component design and also have given us the knowledge on the deformation and thermal handling sections on the piston.
