Abstract: The space-borne manipulator has been playing an important part in the acquisition task of spatial targets, but the docking collision during space capture can easily lead to the instability of both the manipulator and floating base. Aiming at the problem of soft capture, a kind of dual-mode transmission soft-contact joint is developed, which can not only realize the rigid transmission of double degrees of freedom, but also realize the buffering and unloading of space six dimensional collision through damping vibration absorption. The single joint space-based capture mechanism model is established in ADAMS software. The principle of buffering and unloading spatially six-dimensional collision, and the effectiveness for the stability of base and joint, are verified through the comparative simulation of spatially single-dimensional and six-dimensional collision. Furthermore, the model of three joint on-board catching mechanism is established, and the effectiveness of the application of dual-mode transmission soft contact joint in multi joint catching mechanism is illustrated by the simulation experiment in six-dimensional space collision.

Key words: soft capture, dual-mode transmission, damping vibration absorption
