摘要
针对带有多个挠性附件以及天线转动机构的卫星等多体航天器,利用伪坐标L agrange方程建立了系统的姿态动力学模型。通过仿真计算,分析了星体与天线运动的耦合特性,以及挠性附件干扰对卫星姿态的影响,验证了数学模型的正确性。
Lagrange＇s equations in quasi-coordinates are used for dynamics modeling of a multi-body spacecraft consisting of a rigid center body, several flexible appendages and an antenna. The coupling character between the antenna and the center body and the vibration effect of the flexible appendages on the satellite attitudes are analyzed by numerical simulation, which also proves the correctness of the dynamics model.
