| 摘 要： | 为研究非对称结构战斗部的破片飞散特性,利用斜激波理论对爆轰波作用于壳体表面的过程进行研究,并利用自由面速度倍增定律对波在自由面反射后质点速度的计算进行简化,得到了破片飞散角的计算模型。利用D型战斗部试验数据对计算模型进行验证,结果表明,斜激波理论计算得到的破片飞散与试验结果吻合很好;当入射角较小时,壳体飞散角与入射角成线性关系。

| Abstract: | In order to study the projection angles in asymmetrical structure, the oblique shock wave theory was used to describe the process of detonation wave shocking on the metal surface. The calculation method of projection angle was obtained after the velocity multiplication law on free surface simplified the shock wave theory to estimate the velocity of particles in metal. The explosion experiments of a D-shaped warhead had been done to validate this method. The results show that this method is in good agreement with experimental data. And abstractly, when the incident angle is less than 40?, the projection angle will increase linearly with increasing the incident angle. |
