以柴油机组用金属橡胶隔振器为研究对象，运用Pro/Engineer软件对隔振器进行三维建模，并导入 ANSYS Workbench进行网格划分和静力分析，得到金属橡胶隔振器在正向加载、反向加载和径向加载下的等效应力和位移云图，获得隔振器的最大应力值及最大应力位置。结果表明：金属橡胶隔振器的最大应力小于材料的屈服极限，满足设计要求；隔振器壳体底座是容易发生应力集中的部位，容易产生疲劳失效。为节省材料，可以适当减少结构的尺寸，对应力集中的部位可以采用增加倒角的方法进行改善。

Taking metal rubber vibration isolator used in diesel engine set as the research obj ect, a three-dimensional model of metal rubber vibration isolator is established by using the Pro/Engineer software.By introducing the model to ANSYS Workbench software, the mesh generation and static analysis are conducted and the equivalent stress and the displacement nephogram of metal rubber vibration isolator with forward load,reverse load and radial load are obtained.The results show that the maximum stress of the metal rubber vibration isolator is less than the yield limit of material so it meets the design requirements;the shell base of vibration isolator is prone to stress concentration, and easy to produce fatigue failure.The size of the structure can be reduced to save material.For the stress concentration area,it can be improved by the method of increasing chamfer.
