摘要
导弹发射对飞机结构的影响一直是设计师们重点关注的技术之一。本文利用直接瞬态响应分析方法,对某型挂弹飞机在导弹发射过程中的瞬态冲击过程进行仿真,获得机翼的动态力学性能和变化规律,并与静力计算结果对比,阐述动载响应与静载响应的关系。本文的计算结果和相关结论对工程设计具有一定的借鉴和参考价值。
The influences of missile launching on the structure of aircraft have been one of the technologies which designers focus on. In this paper, the direct transient response analysis method is used to simulate the transient impact response of a wing in the process of missile launching. The dynamic mechanics performance and the variation law of the wing are obtained and compared with the static calculation results. The relationship between dynamic response and static response is indicated. The calculation results and the relevant conclusions of the paper have some reference value for actual engineering design.
