摘　　要：利用软件Pro/E建立了磁保持继电器触头系统三维模型,运用有限元分析软件Abaqus对触头系统中柔体部件弹片受力发生形变进行了有限元分析。分析和总结了Abaqus软件在多体系统仿真方面的优势,提出了基于Abaqus的继电器触头系统多体结构建模与仿真方法,对触头系统有限元分析中单元类型的选取、网格划分的技术、边界条件的定义、整体有限元模型的建立等数值模拟技术进行了深入研究,通过添加绑定约束解决了仿真分析中无法达到收敛的问题。对仿真进行了试验验证,结果表明利用Abaqus软件建立的模型能够准确地计算磁保持继电器触头系统中弹片的反力特性。此研究可为磁保持继电器的优化提供依据。A 3D model of contact system in magnetic latching relay was established by the software Pro/E, and the shrapnel deformation by force was analyzed in the contact system using finite element analysis software Abaqus. The advantages of Abaqus software in the multibody system simulation were analyzed and summarized, a modeling and simulation approach to contact multibody system in magnetic latching relay based on Abaqus was proposed. The selection of element type, technology of mesh division, definition of boundary condition, and establishment of finite element model were studied. The non-convergence problems were solved in the simulation analysis by adding binding constraints. The simulation was verified by experiment and it was shown that these models could accurately calculate counterforce characteristics of shrapnel in magnetic latching relay by Abaqus software. The study can provide the basis for the optimization of magnetic latching relay.
