THE DESIGN AND ANALYSIS OF PISTON - STEADY STATE THERMAL ANALYSIS USING “ANSYS”

In this study thermal analysis on piston made of aluminium alloy are absorbed Internal combustion engines have been a relatively inexpensive and reliable source of power for applications ranging from domestic use to large scale industrial and transportation applications for most of the twentieth century. DI Diesel engines, having the evident benefit of a higher thermal efficiency than all other engines, have served for both light- duty and heavy-duty vehicles. But when the piston moves towards Top Dead Centre (TDC), the bowl geometry has a significant effect on air flow thereby resulting in better atomization, better mixing and better combustion. As the main heating part in the engine, piston works for a long time in high temperature and high load environment. The piston has the characteristics of large heating area and poor heat dissipation, so the thermal load is the most serious problem. In this work, the main emphasis is placed on the study of thermal behaviour of functionally graded materials obtained by means of using a commercial code ANSYS on aluminium alloy piston surfaces. Using CREO software the structural model of a piston will be developed. Furthermore, the steady state thermal analysis is done using Computer Aided Simulation software ANSYS.
