摘　　要：为保证在仿真分析中对陀螺稳定平台静、动态性能分析的准确性,必须建立仿真度高而且计算简单的有限元模型。针对平台上零件数量多、种类多、连接形式多的特点,研究建立平台有限元模型的关键技术。分别对轴承、电机、电位计、轴、杆以及零件之间的各种连接作出了合理的简化处理,选取适合的单元种类划分网格,选取满足刚度和强度要求的材料,建立了符合仿真要求的平台有限元模型。为平台静、动态性能分析及结构优化奠定了良好的基础,也为多种零件、多种连接的有限元计算模型简化提供了参考。In order to ensure the accuracy of the static and dynamic performance analysis of the Gyroscope-Stabilized Platform in the simulation analysis,a finite element model with high simulation degree and simple calculation must be established.In view of the characteristics of the platform,numerous parts,many types and various connection forms,the key technology of establishing the platform finite element model is researched. Bearings,a motor,a potentiometer,shafts,rods and the connections between parts are reasonably simplified. All parts are divided by selecting suitable mesh. Suitable materials are selected to satisfy the requirements of stiffness and strength. Therefore,the finite element model of platform is established.This research lays a good foundation for the static and dynamic performance analysis and structural optimization of the platform,and provides a reference for the finite element calculation model with various parts and connections.
