Vibration Response of the Launcher under Impact Load

Vibration of the launcher would cause the initial disturbance of the missile in the launch process. In this paper, the rigid-flexible coupling system model was built on the platform of virtual prototype technology (VPT) based on the improved Craig-Bampton method. Numerical simulation data and experimental results are found to be consistent with each other. Rigid-flexible coupling system was verified to be able to provide valuable results to the research on kinetic, dynamic and vibratory characteristics. Vibration responses of girder and canister under different launching angle are simulated, and results show that increasing launching angle could reduce the vibration of canister and girder.
