| 摘 要： | 选用粒径为587.3 nm的HMX,以LZ12为基板材料设计不同沟槽尺寸,采用精密压装法装药,对超细化钝感HMX在小尺寸沟槽装药条件下的爆轰波传播临界特性进行了研究。结果表明,在设计装药密度为1.77 g.cm-3时,超细化钝感HMX沟槽装药直线传播的临界尺寸约为0.4 mm×0.4 mm,极限尺寸为1.2 mm×1.2 mm,拐直角传播的临界尺寸为0.5 mm×0.5 mm。

| Abstract: | The HMX explosive with particle size of 587.3 nm and precision press loading technique were selected, different sizes of channel were desogned with LZ12. The detonation propagation critical characteristic of superfine desensitived HMX in channel was studied. The results show that the critical size of linear charge is 0.4 mm×0.4 mm, the limit size of linear charge is 1.2 mm×1.2 mm, and critical size of convex charge is 0.5 mm×0.5 mm, when the charge density is 1.77 g·cm-3. |
