发射状态下燃料对FAE战斗部壳体的应力作用分析

The Stress Function of Fuel on the Shell of FAE Warhead During Launching

通过建立力学模型,对FAE战斗部壳体进行了定量分析,提出了FAE战斗部壳体设计的新方法。指出了在FAE战斗部壳体设计中,燃料轴向过载时产生的横向变形对壳体的作用是不能忽视的,这个力和过载加速度引起的轴向力对壳体的作用在壳体的设计中起着主导作用,是设计壳体的主要依据。

By building up a mechanic model, the qualitative and quantitative analysis of FAE warhead shell are introduced in the paper, and a new design method is put forward. The paper indicates that when the fuel is over loaded, the lateral deformation of shell should not be ignored. This force and the axial force caused by the acceleration of over loading should be considered as an important reference in design of shell.
