摘要 针对空间机械臂在运动过程中对其基座产生力/力矩反作用这一问题进行了分析,并提出一种关节轨迹参数化的全局反作用优化方法,用于减小机械臂的反作用力/力矩.基于气浮轴承方法,建立了3自由度空间机械臂反作用优化地面实验系统.最后,采用3自由度机械臂验证了该方法的有效性. When space manipulator moves, it will bring force/torque reactions to the spacecraft. This paper analyzes the problem, and proposes a global reaction optimization method of parameterized joint trajectory, which can reduce the force and torque reactions caused by the space manipulator. Based on air bearings, a ground experiment system for optimizing the 3-DOF space manipulator reaction is set up. At last, 3-DOF manipulator is used to verify the validity of the proposed method.
