Abstract
In this study, thermal stress analysis by shape of piston head was conducted to investigate the shape of a durable piston. As the result, the farther the temperature is from the part where the temperature is applied, the lower the temperature can be seen. Depending on the shape of the piston head, the heated area became different. So, it could be seen that it affected the piston column part and the skirt part. This study showed that three models produced the least stress from the center of the piston head in the same way. Model A showed the smallest stress resulting in the yield compared to the other two models. Model B is a plate type piston head with a concave shape of the piston head, indicating that it is the model that has the least effect on the surrounding area at the center of the piston head. Model C showed the greatest stress resulting from the yield. The results of this study are also thought to be useful for designing the shape of durable pistons. By utilizing the thermal stress analysis due to piston head shape, this study is thought to conform with the aesthetic design.
