抗侵彻过载战斗部模拟装药Hugoniot特性实验研究

Experimental Investigation on Hugoniot Characteristic of Simulated Explosive in Warhead of Protected Overload Against Penetration

通过飞片平面正撞击实验获得了模拟注装TNT炸药在小于1.2 GPa撞击压力下的冲击波速度c和粒子速度u数据,发现在一定的误差范围内实验数据点与注装TNT炸药的Hugoniotc-u曲线接近,说明它们具有相似的Hugoniot特性。因此,在实验研究中可选择与真实装药具有近似Hugoniotc-u曲线的模拟装药代替真实装药进行各种材料动力学研究。

Data of shockwave and particle velocities in the explosive of simulating TNT were obtained by the flyer plate impact experiments at the impact pressure of below 1.2 GPa. Fitted curve of tested data is consistent with Hugoniot c-u curve of real cast TNT in the range of allowable error. So Hugoniot characteristics of the explosive of simulating TNT are similar to that of real cast TNT. In experimental investigation on Hugoniot characteristic of explosive, the simulated explosive may substitute for the explosive in warhead to investigate dynamics of various materials.
