The invention provides a stable adhesion device for spacecraft on-orbit service and a working method thereof.The device comprises a driving system, a flexible adhesion module and a variable-stiffness damper, the driving system is installed on the variable-stiffness damper and connected with the flexible adhesion module, and an external load equipment interface is located on the variable-stiffness damper and connected with the flexible adhesion module; the flexible adhesion module and the variable stiffness damper are provided with adhesion layers of different structures, the adhesion sequence of the different adhesion layers is adjusted according to the structural bearing capacity and adhesion establishment conditions of the different adhesion layers, and stable adhesion and smooth desorption between the flexible adhesion module and a target surface are achieved. According to the invention, the adhesion stability of the load equipment and the target surface under the collision working condition is improved, the vibration energy in the landing process is absorbed through the variable stiffness damper, and the impact is reduced; the driving system provides continuous tangential force for the bionic gecko seta in the landing process, and the adhesion effect of the bionic gecko seta is improved through the resultant force of the tangential force and the normal contact force in the land collision process; and finally, stable adhesion is realized.

    本发明提供一种用于航天器在轨服务的稳定黏附装置及其工作方法,装置包括驱动系统、柔性黏附模块和变刚度阻尼器,驱动系统安装在变刚度阻尼器上,驱动系统与柔性黏附模块相连,外接载荷设备接口位于变刚度阻尼器上,柔性黏附模块和变刚度阻尼器上设有不同结构的黏附层,根据不同黏附层的结构承载能力和黏附建立条件,调整不同黏附层的黏附顺序,实现与目标面间的稳定黏附和顺利脱附。本发明提高了在碰撞工况下载荷设备与目标面的黏附稳定性,通过变刚度阻尼器,吸收着陆过程的振动能量,减小冲击;驱动系统在着陆过程为仿壁虎刚毛提供持续的切向力,切向力与陆碰撞过程的法向接触力的合力提高了仿壁虎刚毛的黏附效果;最终实现了稳定黏附。
