The piston is a critical component of an engine, subjected to cyclic gas pressure and inertial forces during operation. These conditions expose the piston to various fatigue-induced wear such as side wear, piston head cracks, etc. Thus, it is essential for the designer to consider both dimensional and material aspects in the design considerations concerning a piston. This paper describes the procedural framework for designing a piston of a four-stroke engine. A systematic optimization of the same has been done by utilizing on three different materials. Conventionally, the piston is usually made of aluminium alloy, but this paper explores the possibility of using gray cast iron and aluminum silicon carbide composite. It involves modelling on SpaceClaim with further investigations on ANSYS Workbench. The model is analysed on thermal and static loading conditions and the results of the same are recorded numerically and graphically. The validation of the model developed is done by convergence and grid independence. Comparison between the experimental and the standard values are also done to ensure the accuracy of present model for further analysis.

摘要

The piston is a critical component of an engine, subjected to cyclic gas pressure and inertial forces during operation. These conditions expose the piston to various fatigue-induced wear such as side wear, piston head cracks, etc. Thus, it is essential for the designer to consider both dimensional and material aspects in the design considerations concerning a piston. This paper describes the procedural framework for designing a piston of a four-stroke engine. A systematic optimization of the same has been done by utilizing on three different materials. Conventionally, the piston is usually made of aluminium alloy, but this paper explores the possibility of using gray cast iron and aluminum silicon carbide composite. It involves modelling on SpaceClaim with further investigations on ANSYS Workbench. The model is analysed on thermal and static loading conditions and the results of the same are recorded numerically and graphically. The validation of the model developed is done by convergence and grid independence. Comparison between the experimental and the standard values are also done to ensure the accuracy of present model for further analysis.
