摘　　要：首先概述了双轴定位系统工作原理,在对系统结构进行分析、简化的基础上建立了双轴定位系统三维实体模型。其次,详细说明了基于三维实体模型的虚拟样机建模方法。然后,对虚拟样机进行了运动学和动力学仿真,并针对仿真结果进行深入细致分析,为卫星天线双轴定位系统物理样机的优化设计提供了技术支持。Firstly, the work principle of the two-axes position mechanism for satellite antennas is indicated. A solid model of the two-axes position mechanism is built based on the analysis and simplification to the system. Then, the method of building the virtual prototype model based on the solid model is brought forth. Finally, the simulation results and the deep-going analyzing conclusions are showed, which provided the useful suggestions to the optimal design of the physical prototype of the two-axes position mechanism for satellite antennas.
