研究裸弹垂直热发射过程系统的动态响应及其对导弹运动的影响。对车载导弹发射系统进行了简化和等效建模，进行了导弹起飞过程的理论分析，基于动力学和有限元软件建立了系统刚柔耦合多体动力学模型，对发射过程展开了动力学仿真与分析，并进行了多刚体与刚柔耦合两类模型计算结果对比。数值模拟结果表明，导弹起飞过程与发射车的耦合作用明显，系统振动对导弹起飞姿态产生影响，发射车振动衰减特性良好，柔性发射台模型能够较好反映发射过程系统动态响应以及弹架耦合特性。

The missile-launcher coupling and the dynamic response of missile system in bare missile vertical thermal launch process were mainly researched.Simplifying and equivalent modeling were discussed for track-based missile system.The process of missile taking off was theoretically analysed.A rigid-flexible coupling multi-body dynamics model was created based on dynamics and finite element software.The dynamics simulation and analysis were carried out for the process of missile launch.The results of the two kinds of models were compared.The numerical simulation results indicate that the coupling is obvious between the missile and launcher during missile taking off.The vibration of missile system has influence on the taking off attitude.Vibration damping characteristics of the launchers are suitable.The rigid-flexible coupling model can reflect the dynamic performance of missile launch better than the rigid model.
