Abstract:

采用狭缝扫描和激光干涉联合测试的改进标准圆筒试验技术，对比研究了JB-9014（钝感高能炸药）和JOB-9003（高能炸药）两种炸药的做功能力，获得了相同膨胀时间和相同径向位移条件下的比动能。研究结果表明：JB-9014炸药的做功能力明显低于JOB-9003炸药，膨胀速度相对稳定后，相同膨胀时间条件下JB-9014炸药的做功能力基本相当于JOB-9003炸药的68.56%，相同径向位移条件下JB-9014炸药的做功能力基本相当于JOB-9003炸药的69.39%；而且，随着时间的发展或径向位移的增加，两种炸药的做功能力之比有逐渐增大的趋势，与JB-9014炸药的化学反应区较宽且CJ面后仍有可观放能的性质相吻合。
