摘　　要：针对大型车载垂直发射导弹起竖后,地面风载荷会对导弹-发射车系统的稳定性造成影响。本文给出了在导弹起竖后导弹-发射车系统不被吹倒、不发生横向侧移的条件,推导了稳定性的安全系数计算公式;利用单向流固耦合理论,基于FLUENT和ADAMS联合仿真,对导弹起竖后平均风载荷对导弹-发射车系统的稳定性影响进行了分析。结果显示,随着地面风速的增加,导弹-发射车系统被吹倒和发生横向侧移的趋势越来越显著,地面稳定性越来越差。When a large vehicle mounted vertical launch missile is erected, the ground wind load will affect the stability of the missile launch vehicle system. In this paper, the condition that missile launch vehicle system would not be blown down and lateral displacement would not occur after the missile was erected was given, and the calculation formula of the safety factor of the stability was derived. Based on the theory of unidirectional fluid structure coupling and the joint simulation of FLUENT and ADAMS, the influence of the average wind load on the stability of missile launch vehicle system was analyzed. The results show that with the increase of the ground wind speed, the trend of the missile launcher system being blown down and lateral displacement is more and more obvious, and the ground stability is worse and worse.
