摘　　要：利用非线性有限元分析软件Abaqus对机油泵喷油部位橡胶-尼龙-压铸铝合金组合连接件的密封特性进行分析,通过施以螺栓预紧力作用,得到其应力和变形位移。根据橡胶-尼龙-压铸铝合金混合连接件存在的问题,对密封部位的结构进行改进。改进后尼龙喷油管和密封圈的最大Mises应力和最大变形量都大幅降低,能够满足实际密封要求。The sealing property of rubber-nylon-aluminum assemble connections in the jet oil position was analyzed by nonlinear FEM analysis software Abaqus. Stress and displacement distribution were solved through applying bolt preload to the structure. Aimed at the issue of original structure, the structure of sealing connection position was improved. Both maximal Mises stress and maximal displacement for the improved structure were decreased, and it could satisfy the actual sealing requirements.
