This paper describes the stress distribution of an aluminum alloy piston by using CAE Tools. The specifications used for the study of this piston belong to a four cylinder of 1072 cm3 motorcycle engine. The main objectives is to investigate and analyze the equivalent stress, maximum or minimum principal stresses and the total deformation. A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. The piston has the following main function: it takes over the gas pressure force and the mechanical work generated by it and transmits them to the crankshaft, through the motor mechanism. The 3D solid models of piston and piston pin were designed using CATIA V5 R19. They were assembled using Design Modeler from Ansys. The stress analysis results help to improve component design at the early stage and also help in reducing manufacturing time.
