摘要:
文章主要研究了弯曲装药条件下粉状乳化炸药的爆轰特性，并用弯曲装药条件下粉状乳化炸药爆轰速度出现的衰减，即爆速亏损进行表征。试验装置的材料为304钢，钢板上加工有凹槽，粉状乳化炸药装填在不同尺寸的凹槽中，采用爆速仪测量凹槽不同部位装药的爆速。试验发现：粉状乳化炸药的弯曲装药在爆轰过程中存在明显的爆速亏损；在连续的弯曲装药条件下，装药的爆轰出现持续衰减的现象。同时，在弯曲装药条件下，当装药截面积S一定时，爆速亏损随着曲率半径的减小而增加；当装药的曲率半径R一定时，爆速亏损随着装药截面积的减小而增加。而且曲率半径对爆轰传播的影响大于装药截面积的影响。文章通过数据分析，建立了装药截面积S和曲率半径R与爆速亏损之间的关系模型。
Abstract:
Detonation characteristics of powdery emulsion explosive in curved charge were studied experimentally by velocity deficit. In the experiments, powdery emulsion explosive was charged in a curved groove which was machined in steel plates of 304 steel and detonation velocities of the charge in different part of the groove were measured by detonation velocity meter. The results show that curved charge can decrease the strength of detonation continuously, and obvious velocity deficit of the charged explosive is observed. When cross section area S  of the curved charge is fixed,the velocity deficit will increase with the reduction of curvature radius R . When curvature radius R of the curved charge is fixed, the velocity deficit will increase with the reduction of cross section area S. The effect of R to detonation propagation is greater than that of S. The experimental formulas between S, R and velocity deficit were also proposed. 
