| Abstract: | The engineering background and research status of the impact dynamics for flexible multi-body spacecraft structures are introduced.The theoretical model and numerical solution of FMIDASAD software are described,and the computational results are verified by ground test.It is shown that FMIDASAD could capture the main dynamic features of the latching process for flexible multi-body structures,and its predictive impact load amplitude agrees well with test results. |
