摘　　要：为研究在发射筒口加载气幕保护装置后所生成的气幕环境对导弹发射过程中的受力影响,基于气幕环境及动量、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开展了仿真计算,分析了2、3 m/s 2种航速在有无气幕保护时对弹体发射出筒受力影响.结果表明:有无气幕2种工况下,随着航速的增加,指定截面的导弹出筒载荷明显增大,有无气幕2种工况弹体出筒均伴随着较大的振荡过程,气幕对出筒过程力学环境改善作用明显,尤其对于航速2 m/s工况下弹体受力大约降低了50%.研究结果可以应用于相关系统方案设计论证、弹体运动及发射安全性评估.In order to study the affection of the outlet attitude of the missile in the gas screen environment that was installed on the outlet of tube by the underwater missile launching. The underwater missile vertical launching dy- namic model have been created in body coordinate system by gas screen environment and the momentum and mo- ment of momentum theorem, the simulation for the loads of the missile affected by the gas screen and without the gas screen condition, when the submarine velocity was 2 m/s and 3 m/s. The results shown that in the two condi- tions the loads of the missile was significantly increased with the submarine velocity increasing, the outlet of missile was with a large shock process, the mechanical environment improvement with the missile launching process by the gas screen was obviously , especially the loads of the missile was reduced by about 50% when the submarine veloc- ity was 2 m/s. The research result could use in some system method design reasoning,missile motion and launch safety assessment.
