摘要: 针对大型空间设施在轨建造任务需求,以空间多分支机器人为应用对象,设计了一种末端执行器及三种适配接口,用于完成识别、定位、捕获、搬运、装配、攀爬和探测等任务。通过分析在轨建造任务需求,以装配对象参数、机器人性能等为依据提出了设计指标。制定了末端执行器机械结构、电气系统的总体方案,并设计了三种适配接口;针对容差需求,分析了对接过程的容差条件和力学条件,优化了关键部件几何参数;针对锁紧需求,建立了锁紧过程运动学、力学模型,并采用组合运动规律,优化了圆柱凸轮曲线槽。通过仿真及试验,验证了容差、锁紧设计的正确性,并进行在轨装配、在轨攀爬的地面模拟试验,进一步验证了末端执行器及适配接口的性能,为大型空间设施的在轨建造奠定了基础。

Abstract: In order to meet the requirements of the on-orbit construction of large space facilities, an end-effector, and three adaptive interfaces are designed for the space multi-branch robot, which can be used to complete the tasks of recognition, positioning, capture, transport, assembly, climbing, and exploration. According to the requirements of on-orbit construction tasks, design indexes are proposed based on assembly object parameters and robot performance. The overall plans of the mechanical structure and electrical system of the end-effector are being developed, and three kinds of adaptive interfaces are designed. To meet the requirements of tolerance, the tolerance and mechanical conditions of the docking process are analyzed, and the geometric parameters of key components are optimized. To meet the requirements of locking, the kinematic and mechanical models of the locking process are established, and the cylindrical CAM groove is optimized by using the combined motion law. The correctness of tolerance and locking design is verified by simulation and experiment. The ground simulation test of on-orbit assembly and climbing is carried out to further verify the performance of end-effector and adaptive interfaces, which lays a foundation for the on-orbit construction of large space facilities.

Key words: on-orbit construction, space robot, end-effector, adaptation interface, docking and locking
