摘要

In response to the demand for space debris mitigation, this paper discusses an adhesion mechanism based on van der Waals forces and a Stewart platform. This mechanism has high adhesion, high transmission accuracy and high reliability characteristics. The STEWART mechanism adapts to the relative attitude deviation between the service and the target, absorbs the kinetic energy of the collision, reduces the collision force, prolongs the contact time between the adhesion structure and the target surface, improves the impact of non-ideal contact caused by relative attitude deviation on adhesion performance. The system scheme including the mechanism configuration and composition, the adhesive structure and the adhesive material is introduced. In the third section, the collision adhesion dynamic model and the adsorption-desorption behavior model is introduced. The simulation and analysis of collision adhesion performance is detailed explained in fourth section. In the fifth section, through buffer performance testing, adhesion force testing, and air flotation platform experiments, the correctness of the simulation parameter calculation has been verified. The attitude adaptability of the final adhesion based on the non-cooperative target adhesion mechanism of the STEWART platform is determined by the mechanism design, and the adhesion force only plays a role in maintaining adhesion.
