| 摘 要： | 为了研究固体炸药冲击起爆特性，对JO-9159炸药进行了隔板冲击加载实验，用高速摄影方法记录炸药冲击起爆过程；用解析计算方法分析了有机玻璃隔板的临界厚度值；建立了炸药冲击起爆模型，对起爆过程进行了数值模拟，计算了炸药在冲击作用下的压力历史，分析了JO-9159炸药起爆压力阈值和爆轰成长距离。

| Abstract: | For investigating the characteristics of solid explosives initiated by shock waves,the Card Gap Test of JO-9195 explosive was carried out and recorded with high speed camera. The critical thickness of plexiglass clapboard to initiate the explosive was predicted. The shock initiation model of explosives was given. The numeicral simulations of explosive initiation were conducted. The pressure histories inside explosives under shock waves loading were calculated. The threshold pressure to initiate the explosive and the run distance of detonation were discussed. |
