| Abstract: | To approve the reproduction of the relative movement with frequency 0~6 Hz of the docking dynamic simulation experimental testbed,the elastic rod scheme was adopted to reproduce the contact process.By building model and calculation,some design parameters were obtained,such as length of elastic rod,stiffness and spacecraft mass at the same time.The contact force,deformed measure,velocity and reproduce frequency were also analyzed through the simulation of the contact process.The simulation results showed tha... |
