| Abstract: | The stage separating processes of launch vehicle are simulated by Ls-Dyna in this paper.The local FEM models of the linear separation system are built based on the parameters of materials and structures according to the certain design concept.The secondary software based on ANSYS is developed in order to rebuild and analyze the models rapidly and automatically when the model parameters,such as dimensions,materials or boundary conditions,are changed. |
