以跟踪与数据中继卫星为分析对象,建立了整星多柔体系统动力学模型,分析了天线运动作用下,柔性天线和其它附件的综合作用对星本体姿态的影响.结果证明,在分析该中继卫星天线运动对星体姿态影响时,天线的柔性对星体姿态影响很小,在星体姿态控制规律设计中可以忽略,并分析了这种现象产生的原因.
Aimed at a tracking and data realy satellite (TDRS), a dynamical model for the flexible multi-body system of the satellite is established. Influence of the motions of flexible antennas and accessories on the attitude of the satellite is calculated using the model. The results showed that the influence is only trivial and can be neglected when designing on the laws of control of satellite attitude, giving relevant analyses.
