| Abstract: | Coupled rigid and flexible multi-body system dynamics was proposed using rigid multi-body dynamics and flexible body dynamics theories. An ADAMS simulation model was established with the ADAMS and ANSYS software. In this model, flexible launch tubes are referred to. Launching dynamics simulation and analysis of a multiple launch rocket system were performed. Simulation results of the force and the vibration in the whole multiple launch rocket system were obtained. It can be used as a theoretical foundation for investigating dynamic characteristics under the launching process of a MLRS. Additionally, it is of more importance to analyze the initial disturbance and dispersion for MLRS accurately. |
