Abstract

To meet the demand for reusable connection and separation technology in the aerospace field, a space reusable rod-cone-claw type connection and separation mechanism with the advantages of lightweight, limited tolerance, high load-bearing, and high stiffness was proposed in this paper. The static simulation of the space reusable connection and separation mechanism based on ANSYS Workbench was implemented to check its high bearing capacity. The kinematic simulation of the mechanism was conducted by ADAMS software to verify the motion feasibility. Based on the equivalent spring contact model, the display expression of the connection stiffness of the space reusable rod-cone-claw type connection and separation mechanism was established. The stiffness values of the reusable connection and separation mechanisms under the condition of no preload and only under the condition of preload were analyzed using ANSYS Workbench software, and the first-order polynomial function was fitted to the stiffness. Combined with the linear programming method, the preload value was optimized to maximize both stiffness and load-bearing capacity. Finally, the principal prototype of space reusable rod-cone-claw type connection and separation mechanism was developed, and 10 repeated connection and separation experiments were carried out to prove the effectiveness of the design. The design of the space reusable rod-cone-claw type connection and separation mechanism provides theoretical and technical support for its application in engineering applications such as aircraft rendezvous and docking, satellite on-orbit service, antenna repeated deployment, and large-scale aerospace structure on-orbit construction.
