Abstract :
A four-cylinder diesel engine model is established using Pro/Engineer 3D modeling software. The model is loaded by ANSYS software. Grids meshes are imposed to the model with contact-settings and boundary conditions. Finite element analysis is performed on the contact-state of the diesel engine body. According to the minimum-zone principle for the flatness error analysis, Particle Swarm Optimization algorithm (PSO) is applied, and the mathematical model and method of the engine body top-surface-flatness error analysis is established. Based on the established method, the engine body top-surface-flatness errors can be obtained under the maximum preload working conditions, providing an accurate and effective way for further improvement of the engine tightness and body design.
