两次脉冲加载条件下炸药装药的安全性实验技术

为获得炸药装药在多次脉冲载荷条件下的安全性，基于大型落锤模拟加载装置，设计了两次脉冲实验装置，建立了两次脉冲载荷条件下炸药装药安全性实验方法。研究了CL-20基含铝炸药在两次脉冲载荷条件下的安全性。结果表明:所用的实验装置可以对CL-20基含铝炸药装药实现两次脉冲，实验原理可行。锤头高度为1.0 m时，炸药装药在两次脉冲载荷作用下未发生点火;锤头高度超过1.2 m后，炸药装药在第二次脉冲载荷作用时发生点火。

Experimental Technology of Safety of Explosive Charge under Two Pulse Loading Conditions

In order to obtain the safety of explosive charges under multiple-pulse loading conditions, based on a large drop weight simulation loading device, two-pulse experimental devices were designed, and the experimental technology of explosive charge safety under two-pulse loading conditions was established. The safety of CL-20-based -aluminum-containing explosives under two-pulse loading conditions was investigated. Results show that the device used in the experiment can achieve two pulses to CL-20-based aluminum containing explosive charge, and the experimental principle is feasible. When the hammer height is 1.0 m, the explosive charge does not ignite under two pulse loading. But when the hammer height exceeds 1.2 m, the explosive charge ignites at the second pulse loading.
