切向爆轰驱动下板折转运动的实验观测分析

EXPERIMENTAL MEASUREMENTS AND ANALYSIS ON THE DEFLECTION MOTION OF A METAL PLATE UNDER SLIDING DETONATION

在本工作中采用同轴电探针技术对切向爆轰作用下金属板的折转角β及运动速度进行了测量,并利用锰铜压阻传感器对炸药一金属板分界面处压力随时间的变化历程进行了同步记录。采用二维特征线法在取γ=2.91时所做的数值计算结果与实验数据达到了良好的一致。

The deflection angles β of metal plates driven by the sliding detona tion were measured by use of the coaxial probe technique, and the pressure-time history on the metal-explosive interface were recorded by the Manganin piezo-resistive method. The results of numerical analysis show very good agreement with the experimental data, using adiabatic exponent γ=2.91 by the bicharacteristic method.
