Piston is an important component of the motor vehicle that can pump or result in a pressure thus enabling to generate the components to reciprocate the engine. Commonly, it is made of mixed aluminum in which in the work process of engine, it receives the high level of pressure and heat that later emerges the pressure on the surface. To observe the distribution of the surface pressure on the piston due to the high pressure and temperature, it cannot be manually done but by means of the approach of the finite element method through the Ansys sofware. The variation of the simulated surface pressures consisted of 5, 10, 15 and 20 MPa with various pedestals given. Based upon the simulation result, it was found that the variety of the pressures received by the piston surface has caused the level of pressure experienced by piston also changed. It was similar with the result of the use of different positions of pedestals in which it could lead to a change in the pressure concentration of piston. © 2016 Author(s).
