Research on Dynamics Simulation of Buffering Process of Docking Mechanism

摘要

On-orbit service technology can extend the working life of the spacecraft, and improve the ability to perform various tasks. Docking mechanism is the key equipment of the space docking. The cushion performance of the system determines the dynamic characteristics in the docking process, and it is one of the important factors influencing the docking success or not. It is established that mathematical modeling of the new grasping mechanism in the buffering process, due to lack of the experiment equipments, the dynamic simulation on computer is an effective method to test and verify the parameters or evaluate the performance of the buffer system designed. Simulation analysis is conducted to get the corresponding buffer force for four different sets of buffer parameter, and it provides important basis for docking cushioning structure optimization.
