Aiming at the problem of short lifetime and high cost in the on-orbit Servicing technology, a new type of automatic autonomous probe-cone docking mechanism used for microsatellite docking is proposed which can realize on-orbit special services. The structure of the mini docking mechanism is provided according to the design indices, and a virtual prototype model of the mini-type universal docking system is established by using MATLAB software. The dynamics modeling of the docking process is presented based on the virtual work principle. The simplified dynamic analysis model during the capture process is established. The dynamic characteristic analysis of the catching process is completed to research the influence of the key parameters, and the virtual prototype model of the docking device is established through ADAMS for further verifying the proposed design. The analysis shows that this mechanism has the good capacity of capture and separation process and energy absorption to reduce the impact during the docking process. And the simulation results meet the design demands of mini-type universal autonomous docking mechanism.
