潜射导弹发射装置发射时的结构动力学分析

Structure Dynamic Analysis on SLS When Launching

导弹水下发射产生巨大的反冲击力,引发潜艇本体以及发射装置的强烈振动,对发射装置的结构强度、筒内导弹的安全和下一枚导弹的发射产生不可忽视的影响。基于结构动力学基本理论和有限元法,分析了系统发射时的振动特点、问题难点和外载荷情况。对潜射导弹发射装置结构动力学模型进行有限元计算做了理论分析和方法步骤的探讨,基本解决了系统建立思路问题。

When launching, the great power brings on acute vibration to both the submarine and the Submarine Launch System （SIS）. Then the vibration has great effect on the structure intensity of the SIS, the security of missile and the launching of next missile. Based on Structure Dynamic Theory and Finite Element Method, the vibration character of the launching SIS, the difficulties and the loads are analyzed. The theoretical analysis as well as its approach and steps is also discussed as to finite element calculation of structure dynamic model for submarine missle launch system. The question of how to establish the system has been fundamentally solved.
