基于发火可靠度裕度的生产方风险分析

Producer Risk Analysis Based on Margin of Firing Reliability for Initiating Explosive Devices

基于火工品感度分布模型及GJB376-87给出的火工品发火可靠度裕度系数定义,推导出了生产方风险与火工品发火可靠度裕度系数之间的定量关系式。利用该关系式和升降法试验,求得某针刺雷管发火可靠度裕度系数为1.74,生产方风险为0.003%;某电雷管发火可靠度裕度系数为1.48,生产方风险为0.00096%。结果表明,本文给出的这种定量关系与实际产品相符。

Based on sensitivity distribution and the definition of margin of firing reliability for initiating explosive devices given in GJB376, the quantitative relationship between producer risk and margin of firing reliability of initiating explosive devices was deduced. According to the relationship and up-and-down method test data, the margin of firing reliability and producer risk of a stab detonator are 1.74 and 0. 003% respectively, and the margin of firing reliability and producer risk of an electronic detonator are 1.48 and 0.00096% respectively. Results show that the quantitative relationship between producer risk and margin of firing reliability of initiating explosive devices is accordant with practical products.
