| 摘要: |
| 进行了两类压剪加载实验:(1)利用石英的平面正碰撞产生压剪加载的实验，采用电磁质速法测试装药试件内部不同质点的运动情况，分析炸药装药中发生化学反应的可能性；(2)在压剪炮上采用平行倾斜碰撞产生压剪加载的实验，观测炸药装药爆炸的可能性。由实验可以看出：在亚爆轰状态的压缩加载应力条件下，剪切的联合作用对炸药的起爆起到敏化作用，适当比例的压剪加载造成更加敏感的炸药起爆响应。文中给出了起爆响应规律和响应机制的实验分析。 |

| Abstract: |
| The initiation Speculiarity of the solid explosive charges under combined compression-shear loading is investigated in this paper. Two kinds of experiment about compression-shear loading have been carried out，one is the experiment in which compression-shear loading is realised by using the normal impacting quartz，and the possibility of chemical reaction taking place in the charges is analysed according to the movement of different partictcs inside the charge specimens measured dy means of electric-magneti particle velocity method；the other is the experiment in which the loading is realised by means of parallel inslant impact method on the compression-shear gun，and the possibility of charge explosion is observed. The experiments show that when the compression stress is under condition of sub-detonotion,the shear stress combining in the loading will play, a role in sensitization of the charge initiation a more sensitive initiation response of explosive is caused by the compression-shear loading under moderate proportion. Experimental analysis of rules and mechanism of the initiation response of explosive is presented in the paper |
