基于概率浮动的战术导弹载荷设计方法研究

Study on the Load Design of Tactical Missile base on the Probability Exchange

为了保证导弹飞行载荷设计工况的同时性和覆盖性要求,针对现有方法在这两点上不能完全满足的缺点,在使用载荷概率设计的大思路下,本文提出了基于概率浮动的导弹载荷设计工况挑选方法。采用浮动概率值,在弹道筛选工况点附近增加计算工况,弥补了由于弹道专业和载荷专业输入不一致而导致的载荷计算结果覆盖性不足的问题。通过算例分析对比,得出本文方法在过载计算值上对不同输入计算后的过载工况覆盖性超过75%,弯矩载荷计算最大值可以覆盖设计要求。

To solve the shortage of traditional method where the design load of tactical missile cannot satisfy the simultaneity and coverability, the load design of tactical missile base on the probability exchange is put forward. The calculation case for load design is increased while the method of probability exchange is used, which can fetch up the problem which is due to the different input of the trajectory calculation and the load calculation. It is found that coverability of the over loading using the method in the paper can be increased excessive 75%, and the moment load can cover with the design requirements.
