Реферат
(EN) The invention provides a space mechanical arm suspension microgravity simulation device, which belongs to the field of simulation experiments, and comprises a mechanical swing arm mounting platform, asix-degree-of-freedom table and a camera, a target point on the six-degree-of-freedom table is measured in real time to obtain the position and attitude change of the six-degree-of-freedom table, andthe mechanical swing arm mounting platform is controlled to move along with the six-degree-of-of-freedom table; the mechanical swing arm mounting platform comprises an omni-directional moving platform, a balance weight and a mechanical swing arm bracket; the omni-directional moving platform moves omni-directionally in a plane; a counterweight, which is used for balancing the whole centroid of theomni-directional mobile platform, and a mechanical swing arm, the motion of the mechanical swing arm bracket is used for compensating the motion precision of the full-moving platform. The action of the gravity of the mechanical arm on the posture of the spacecraft when the mechanical arm is unfolded is eliminated, meanwhile, more motion freedom degrees and motion ranges of the mechanical arm arereserved, and the unfolding range of the space mechanical arm is adapted to in a large range.
(ZH) 本发明提供了空间机械臂悬吊微重力模拟装置,属于仿真实验领域,包括机械摆臂安装平台、六自由度台和相机,实时测量六自由度台上的靶标点,得出六自由度台的位置与姿态变化,控制机械摆臂安装平台跟随六自由度台运动;机械摆臂安装平台包括全向移动平台、配重与机械摆臂支架,全向移动平台在平面内全向移动;配重;用于将全向移动平台与机械摆臂的整体质心配平;机械摆臂支架,其运动用来对全移动平台的运动精度进行补偿。本发明消除机械臂展开时自身重力对航天器姿态的作用,同时保留机械臂较多的运动自由度及运动范围,较大范围的适应空间机械臂的展开范围。
