    摘要:

    以空气隙长度为变量设计了用于确定空气隙传爆界面可靠性的试验方案, 并构建了试验装置。采用Neyer-D最优化法,试验并估算了隔板起爆器中由雷管、空气隙和导爆药组成的空气隙传爆界面的可靠性。结果表明,空气隙的临界起爆长度为18.76 mm。由p分位数的区间估计所得的置信度为γ=0.95的界面作用可靠度为0.999925。

    Abstract:

    Determination test of the reliability of air gap detonation transmission interface was designed through air gap length as variable and testing device were constructed. The reliability of air gap detonation transmission interface composed of including detonator, air gap and detonating explosive in partition initiator was tested and estimated by Neyer-D Optimized method. Results show that the critical functioning length of air gap is 18.76 mm. The reliability of the interface function obtained by interval estimation of p quantile is 0.999925 at confidence level of γ=0.95.
