端面起爆驱动圆柱壳体的分析

Study on Cylindrical Shell Driven by Detonation Ignited in End

文中通过对基本的爆轰理论推导,并考虑稀疏波的影响,根据实际情况推导了端面起爆驱动圆柱壳体的破片速度分布,可以看出其速度值的最大分布区域与通常的观点有差异,并提出了三种爆轰场等场强作用的形成方法。该理论分析结果可为爆轰加载研究及战斗部工程设计提供有益的参考。

In the paper the distribution of fragments＇s initial velocity was deduced on driven by detonation ignited in end, which the influence of rarefication wave was considered by using fundamental detonation equations for real state. It is different between the results of the paper and the traditional concept for distribution region of maximum initial velocity of fragments. The results were analysised and obtained some useful conclusions such as operation methods of equal detonation intensity. It is worthy of apply on investigations of warhead engineering and detonation study.
