| 摘 要： | 活塞是发动机的核心部件，其设计是否合理直接关系到发动机的可靠性、耐久性和经济性。本文在2007年3月发布的Ansys 11．0协同仿真环境中建立了详细的活塞三维实体模型，运用第三类热边界条件，结合热耦合分析方法完成了活塞的三维温度场，位移场及热应力场的仿真，在此基础上对活塞的结构优化进行了探索，并设计出一款性能得以改善的活塞，实现了真正意义上的仿真驱动产品设计。

| Abstract: | Piston is one of the most important parts of the Engine.The reasonable design of piston directly relates to the reliability,durability and economic performance.A detailed three-dimensional solid model of the piston is established by means of Ansys 11.0 Workbench Environment(AWE),which is issued in March 2007.Using the third thermal boundary conditions,analysis of the three-dimensional piston,including temperature,displacement and thermal stress field are performed by means of thermal-structural coupling.Structural optimization is also accomplished and a new piston has been designed,which performance is getting improved. |
