Analysis of Piston Optimization Design Based on Finite Element Analysis

To satisfy the need for designing high speed and light weight pistons,optimization analysis and design must be performed on pistons under intension range.Using optimization design method based on finite element analysis,finite element analysis of the piston is made in this paper.Then the influence of two dimension parameters on piston stress and deformation is analyzed.After analyzing the parameters which influence piston stress greatly,the piston optimization design with the goal of minimizing total mass is accomplished.After optimization,the weight of piston reaches the minimum within admissible stress and the design requirement is achieved.
