| 摘 要： | 建立了卫星在轨自维护系统的结构模型.基于动量守恒定律,建立了自维护系统末端操作器速度与卫星本体速度及机械臂各关节速度之间的关系.以操作太阳帆为例,对机械臂的运动与卫星本体姿态变化之间的关系进行了仿真分析.仿真结果表明,机械臂运动速度对卫星姿态不产生影响,而机械臂转动角度决定了卫星姿态.

| Abstract: | The sketch map of a satellite model and robot arm is built up. In terms of the law of conservation of momentum, an expression is set up that indicates the relationship between the manipulator speed and satellite and robot arms movement. Under the environment of micro-gravity, the operation of sun mirror of satellites is simulated. The result showed that the rotating speed of arms does not affect the final position of satellites and that the angle rotated decides the final position of the satellite. |
