Abstract
A flexible multi-body dynamic model of ship-based missile vertical launching system (VLS) was built on the platform of virtual prototype technology (VPT), based on finite element method (FEM) and improved fixed-interface substructure modal synthesis. The dynamic simulation of the flexible model was performed, and the results were compared with that of the rigid model. The trajectory and attitude deviations during launching were gained. The analysis of effects of flexible deformation on initial trajectory characteristics and launch security was completed.
