摘　　要：对卫星挠性太阳阵附件模态在轨激励仿真分析进行了研究。用星上控制执行机构激发卫星各阶模态。将旋转附件和挠性附件统一视作挠性旋转附件,对整星刚柔耦合动力学进行建模。仿真结果表明,执行机构周期性作用可激发出太阳电池阵的各阶模态,与有限元计算结果基本一致。The simulation analysis on on-orbit incentive of modal frequency for satellite flexible solar array was studied in this paper. The mode of the satellite was excited by the onboard control actuators. The rigid-flexible coupling dynamic model was build with the rotation accessory and flexible appendage viewed as one appendage. The simulation results showed that every mode of solar array excited by actuators was basically identical with the finite element calculation.
