Mechanical Study on Rigid-flexible Coupling Capture Unit Based on Gecko-inspired Dry Adhesion
To solve the space dynamic capture problems in on-orbit operations such as space debris removal and non-cooperative satellite capture,a rigid-flexible coupling adhesion capture unit based on the gecko-inspired dry adhesion was designed to achieve stable adhesion to the target surface un-der impact contact.A mathematical model was established to analyze the dynamic characteristics of the adhesive impact.A performance testing device was built to measure the relationship between pa-rameters such as the collision/detachment force and speed of the adhesion unit.Dynamic mechanical properties of adhesion capture-detachment were analyzed and a strategy of parameter settings for the adhesion capture in a microgravity environment was summarized.Finally,the adhesive self-captu-ring ability in microgravity was verified by the experiment of parabolic flight,which shows that the developed adhesion device can meet the application requirements of space capture.
