Design of S.I Engine Piston and Thermal Analysis with Different Materials by Usign Fea

Abstract

The project MODELLING AND ANALYSIS OF PISTON in S.I engine according to the forces acting on it from the gases, which are released during the combustion. The piston head acts as a particular case and hence the piston is analyzed for the stresses developed due to the conditions.

           At first, the piston is designed according to the specifications. After the designing, the model is subjected to certain conditions. Mainly piston is connected to connecting rod and that connecting rod is engaged to crank shaft. According to the conditions we have checked the stresses acting on it and checked analysis of the model. After the analyzing the changes are done to the model if required.

In the analysis a model of piston of the s.i engine is generated using software CATIA, the analysis of the piston is generated using Ansys. It will takes thermal analysis on piston with different materials and find the heat flux. The result are calculated and tabulated below and the heat flux acting on the body are shown using with different materials (aluminum alloy and aluminum oxide (composite material)).
