Attitude simulation of launch process of vehicular missile

To research the dynamic response of the system and movement characteristic of the missile during launch process of vehicular missile, the system vibration characteristic was analyzed theoretically. The missile movement disturbance principle was analyzed comprehensively. The rigid-flexible coupling dynamic model was created based on simplified launch system. The impact force of jettison and jet flow were considered in the model. The rigid-flexible dynamic simulation for the whole launch process was carried out. Simulation results and experimental results are identical with each other. The study results show that the launch process of missile can be simulated well by the created rigid-flexible coupling dynamic model. The damp design of the whole system is basically reasonable, and the tactical requirements can be satisfied.
