摘　　要：根据非电传爆序列设计基本要求及火工装置可靠性估算方法,对使用起爆药的传爆序列进行了可靠性评估及分析,得到敏感起爆药与钝感猛炸药交叉使用,是降低系统安全性及可靠性的主要因素。通过传爆药钝感化、减少传爆界面个数、调整装药参数等措施,完成了非电传爆序列优化设计,并对优化后传爆序列进行了可靠性评估,设计了可靠性试验及可靠性增长试验。结果表明,优化设计不仅提高了传爆序列安全性,而且使传爆可靠度由0.99提高到0.9999(置信度γ=0.7),能够给非电传爆系统提供高安全、高可靠的传爆组件。According to the basic requirements of non-electric stimulus detonating train and the reliability assessment methods of initiating devices, the reliability of detonating train of the initiator was evaluated and analyzed. The safety and reliability of the system can be decreased by means of alternative application of sensitive initiator and insensitive explosive. Optimization design of non-electric stimulus detonating train was finished through passivating the initiator, decreasing the number of detonating interfaces and adjusting charge parameters. In addition, the reliability of the optimum detonating train was evaluated, and the reliability test and the reliability augmentation test were designed. The results show that optimization design can not only improve the safety of detonating train, but also make the detonating reliability increase from 0.99 to 0.999 （ confidence level γ = 0.7 ）, which can provide safe and reliable detonating unit for non-electric stimulus detonating system.
