摘　　要：研究了大型跟踪与数据中继卫星动力学建模问题。首先结合模态综合和混合坐标方法介绍了中继卫星柔性动力学一般模型建立过程;根据工程需要重点对所建立的一般动力学模型利用模态综合进行降阶处理,给出了工程实用的低阶动力学模型和各耦合系数的计算表达式;最后通过一个工程实例对模型进行了验证。A dynamic modeling method for the tracking and data relay satellite （TDRS） is investigated in this paper. The TDRS considered consists of a main rigid body to which a number of flexible multibody appendages are attached. Firstly, a general dynamic model for TDRS is derived by using the hybrid coordinate and component modal synthesis. Then the model is reduced to be a low order one. The model and flexible coupling coefficients developed can be used for analysis and simulation of many TDRSs. Finally, the effectiveness of the proposed method is demonstrated by an example of TDRS.
