Abstract

As the research object to a certain type of diesel engine pistons, a three-dimensional finite element analysis model is established. Piston stress is calculated under the conditions of thermal load, mechanical load and coupled load. Results show that, the main cause of the piston safety, the piston deformation and the great stress is the temperature, so it is feasible to further decrease the piston temperature with structure optimization.
