摘要

在拟合冲击波散逸能量的分布的基础上,利用散逸能量密度、衰减系数等,给出了两个装药延时起爆时冲击载荷的计算方法。通过引入一种新型冲击因子,提出了两个装药延时起爆时水下目标的毁伤评估方法,最后利用试验数据估计出目标毁伤时冲击因子的临界值。结果表明,冲击载荷计算方法正确,冲击因子能较好的反映目标的毁伤情况

Abstract

In this article, on the base of fitting emission distribution of shock wave’s energy, the method to calculate the impulsive loads of two charges’ shock wave is given by using the emission energy density, damping coefficient etc. Then, a damage evaluation method is proposed through introducing a new impulsive factor. By using testing data, the critical value of impulsive factor about damage target is estimated. The result shows the method to calculate the impulsive loads is correct, and the target’s damage state can be reflected well by the impulsive factor.
