摘要：

摘要：  运用非线性有限元法对国内自主研发的桩腿耦合缓冲器（LMU）试验模型进行了数值分析，讨论了LMU的载荷位移关系和应力分布特点，并与模型试验的测点应力和位移进行了比较.比较结果表明非线性有限元法的计算结果与试验结果较为吻合，非线性有限元法可用于LMU结构的设计和开发.

Abstract:

Abstract： In this paper, numerical analysis of a domestically developed leg mating unit (LMU) test model was conducted using nonlinear FEM. The characteristics of the loaddisplacement relationship and stress distribution were discussed. The stress and displacement in the measurement points were compared with the model test results. The comparison indicates that the results of nonlinear FEM agree well with the model test. As a consequence, nonlinear FEM can be applied in the design and development of LMU. The method and the conclusion can provide reference for the design and analysis of LMU.

Key words: leg mating unit (LMU), test model, rubber, nonlinearity, contact, numerical analysis
