摘　　要：文中应用有限元数值计算方法,建立了捷联惯测组合台体结构的三维有限元模型,分析计算了其静、动态特性,给出了台体结构在大过载环境下的应力和变形图和0～2000Hz 内的固有频率及振型,并对如何提高台体结构的动态性能提出了建议,为其进行进一步的动力学分析奠定了基础。This paper established a 3D finite model of Combined Strap-down IMU Platform structure using FEM.Its static/dynamic characteristics is assayed and the stress and strain diagram under large overload are given.Also,the paper pointed out its natural frequency and modal shape within 0～2000Hz.At last,Some suggestions for the improvement of the platform structure dynamic properties are proposed.So a base for the dynamic analysis study for the platform is provided.
