摘要：

With a focus on the difficulty of dynamic modeling of missile launchers, a multibody system analysis method is adopted in this paper to deduce the total transfer equation of the system by establishing the topological diagram of the launcher structure and the transfer equation between the components. To study the influence of initial disturbance factors on missile launching accuracy, a multibody and rigid flexible coupling simulation system is designed by using automatic dynamic analysis of mechanical systems and Creo on the basis of dynamic analysis of the model by using the transfer matrix method of multibody system and rigid flexible coupling theory. Simulation results show the following: the rigid-flexible coupling system can absorb vibration; a large launch interval and small locking force correspond to a small initial disturbance of the missile and high launching accuracy; and the model of adding gas flow force can reflect the actual launching process of the missile more accurately. © 2022 Editorial Board of Journal of Harbin Engineering.
