摘　　要：星载机械臂在执行在轨捕获任务时,抓捕碰撞力过大或动量传递过快都易对航天器基座的姿态稳定造成破坏。为减少空间对接冲击的影响,开展空间捕获柔顺对接研究,设计一种空间四自由度软对接机构,以陀螺结构组件的三维旋转缓冲碰撞冲量,通过可控阻尼吸振实现空间六维碰撞的卸载;研制空间陀螺柔顺对接机构的原理样机,并在地面微重力气浮平台上,开展碰撞模拟实验,实验结果表明所提出的空间陀螺柔顺对接机构可缓冲卸载航天器六维碰撞冲量,避免基座失稳。When the spaceborne robotic arm performs in orbit capture tasks,excessive collision force or rapid momentum transfer can easily cause damage to the attitude stability of the spacecraft base.To reduce the impact of space docking impact,research on space capture compliant docking is carried out,and a space four degree of freedom soft docking mechanism is designed.The three-dimensional rotation of the gyroscope structure component is used to buffer the collision impulse,and the unloading of space six dimensional collisions is achieved through controllable damping and vibration absorption;Develop a prototype of a space gyroscope compliant docking mechanism and conduct collision simulation experiments on a ground microgravity air floating platform.The experimental results show that the proposed space gyroscope compliant docking mechanism can buffer and unload the six-dimensional collision impulse of the spacecraft,avoiding base instability.
