摘要: 针对耦合影响较严重的天线回扫过程展开研究.首先,将柔性支撑杆等效简化为悬臂梁结构,并基于拉格朗日方程建立多体耦合动力学模型.然后从耦合动力学模型出发,分析天线回扫运动对星体姿态稳定和柔性振动的影响,并根据分析结果引入命令预处理算法,规划天线回扫指令.最后对天线回扫运动进行仿真分析,仿真结果表明命令预处理算法能够有效地减小回扫运动对星体姿态稳定和柔性振动的影响.

Abstract: The coupling of satellite attitude motion and antenna flexible vibration has more influence on the antenna slewing, which is examined in this paper. First of all, the flexible boom is simplified as an equivalent cantilever beam structure, and the multibody coupling dynamics is established based on the Lagrange equation. Then the impacts of antenna slewing motion on attitude stabilization and flexible vibration are analyzed according to the coupling dynamic model. Based on the analysis results, the command preprocessing algorithm is introduced to plan the antenna slewing process. Finally, simulation analysis is performed for the antenna slewing motion. The simulation results show that the command preprocessing algorithm can effectively reduce the influence of the slewing on attitude stabilization and flexible vibration.

Key words: intersatellite link antenna, flexible multibody satellite, slewing movement, command preprocessing
