摘　　要：导弹在潜艇带速水下垂直发射出筒过程中涉及复杂的力学问题,弹体在出筒阶段受到适配器的约束,并受到其施加的横向支撑反力,使得出筒阶段弹体载荷水平较高。依据动量和动量矩定理建立了导弹水下垂直发射出筒过程动力学模型,并对艇速为1.5 m/s、2.5 m/s时两种横向支撑方式对导弹的出筒过程中的力学特性开展了仿真计算。结果表明:两种横向支撑方式下,适配器方式的出筒姿态较好但是弹体受到的载荷更大,此外气密环-减震垫横向支撑方式下,弹体出筒伴随较大的震荡过程,在今后研究中必须要重视振动问题。An underwater missile vertical launching was affected by its carrier-a moving submarine, it involved complex problems of mechanics. The missile was constrained by a adapter, and it suffered a transverse support force exerted by the adapter, so the missile body had a higher load level out its launch tube. The dynamic model for underwater missile vertical launching was built in the body coordinate system with momentum and moment of momentum theorems. The mechanical characteristics of the missile contrained by two kinds of adapter were simulated with submarine velocities of 1.5m/s and 2.5m/s. The results showed that under two kinds of transverse supports, the missile has better outlet attitude but more loads ; furthermore, for seal-pad transverse support, the missile outlet is with a larger shock process, and vibration problems should be paid to much attention.
