| Abstract: |
| Objective To ensure launching safety and provide accurate initial outlet attitude parameters for robust design of exterior trajectory. Methods Launching dynamic modeling and simulation technology was proposed to study influences of ship swaying motion on missile launching outlet attitude. The rigid-flexible coupling multi-body dynamic model was built based on topology structure of concentric canister launcher system. The flexible body models of launcher and missile were built through the Craig-Bampton modal synthesis method. The contact collision between missile and launcher was simulated through nonlinear spring damping. The thrust model was built with AKIMA interpolation method based on engine test data. The roll, pitch and sway motion of ship were simulated through sinusoidal function. Results The research was made on a series of working conditions influence on missile launching outlet attitude. Through this research, some useful values of key design parameters which were difficult to be measured in physical tests were obtained. Conclusion The research results show that the reasonable sliding block distance and sea wave level can effectively ensure launching security of concentric canister launcher system. The research results have important engineering value for the design of concentric canister launching system. |
