| 摘 要： | 利用ANSYS将495Q型发动机活塞建立有限元模型,进行模态分析。得到了活塞在自由状态固有频率和模态振型进而确定活塞的振动特性,并根据得到的几阶振型图分析应力状况,找出活塞相对应力集中处,最后对活塞裙部的形状进行优化改进。通过分析和改进,使活塞的动力学特性更加合理。

| Abstract: | The 495Q type using ANSYS finite element model engine piston, modal analysis. Got the Pistons in the free state natural frequencies and mode shapes and to determine the vibration characteristics of the piston, and according to several vibration modes resulting stress state diagram analysis to identify the piston relative stress concentration, the final shape of the piston skirt to optimize improvements. By analyzing and improving the dynamics of the piston is more rea- sonable. |
