摘　　要：根据机械冲击式主动消旋方法的特点,设计了变压力柔性冲击末端.考虑到变压力柔性末端的流固耦合作用,通过分析内部气体压力对末端刚度的影响,确定了压力阈值并展开优化设计.对柔性冲击末端与空间碎片之间的碰撞力进行了理论分析与实验研究,建立了柔性末端与空间碎片碰撞的接触模型,设计了冲击与测量实验系统,修正了摩擦模型,通过冲击实验验证模型与实验结果吻合较好,法向碰撞力和切向摩擦力模型计算误差分别小于6.7%和6.9%.研究表明变压力柔性末端设计合理有效,满足空间碎片消旋要求,对发展空间碎片捕获方法具有重要指导意义.According to the characteristics of the mechanical impact active detumbling method,the variable pressure flexible impact end-effector is designed.Considering the fluid-solid coupling effect of the end-effector with variable pressure,the threshold is determined and the optimal design is developed by analyzing the influence of the internal pressure on the stiffness.The theoretical analysis and experimental research on the collision force between the flexible impact end-effector and the space debris are carried out.The contact model is established.The impact and measurement experimental system is designed and the friction model is corrected.The impact test proves that the model agrees well with the experimental results and the calculation errors of the normal collision force and the tangential friction model are less than 6.7%and 6.9%,respectively.The research shows that the flexible end-effector is reasonable and effective,meets the requirements of space debris race-off,and has important guiding significance for the development of space debris capture methods.
