摘要:
研制了适用于PBX炸药体膨胀的测试装置。采用此装置分别对热固型与热塑型PBX炸药的体膨胀力进行了测试，获得了两种炸药由常温升至75 ℃时的体膨胀力和体膨胀力随温度的变化曲线。试验结果表明，两种炸药的体膨胀力均是随着温度的升高而增加，在60～70 ℃范围内体膨胀力增加最大。炸药类型对炸药的体膨胀特性有较大的影响，热塑型PBX的体膨胀力远远大于热固型PBX的体膨胀力，是热固型炸药体膨胀力的8～9倍。对比不同质量的PBX-A炸药试验结果发现，随着炸药质量的增加，炸药体膨胀力随之增加；对体膨胀力-质量曲线进行线性拟合发现，体膨胀力随着质量的增加基本呈线性增长趋势。
Abstract:
Testing device used to investigate volume thermal expansion of PBX explosive was designed. Thermal-curing PBX explosives and thermal plastic PBX explosives in the same size, and thermal-curing PBX explosives in different weights were tested. Volume thermal expansion strength and volume thermal expansion strength curves of these PBX explosives changing from room temperature to 75 ℃ were obtained. Comparing volume thermal expansion performance of thermal-curing PBX explosives with the thermal plastic PBX explosives in the same size, it was found that volume thermal expansion of both of these two PBX explosives increases with temperature, reaching the maximum at 60-70 ℃. The type of PBX explosive has great influence on volume thermal expansion performance. It has been concluded that volume thermal expansion of thermal plastic PBX explosives are far larger, which are 8-9 times, than that of thermal-curing PBX explosives. From test result comparison of PBX-A explosive with different weights, it was found that volume thermal expansion increases with weight of PBX explosive. In volume thermal expansion-weight fitting curve, volume thermal expansion increases linearly with the weight of PBX explosive.
