计算机模拟步进法感度试验研究

利用计算机模拟试验对步进法感度试验中步长与试验样本量的合理选取问题进行了研究.结果表明,当每个刺激量下的试验样本量达到200发以上,在总试验样本量为2 000～3 000发的条件下,就能较为准确地实现火工品感度分布模型检验,对今后的火工品步进法感度试验有一定的指导意义.

Study on Run-down Method Sensitivity Test by Computer Simulation

Some key questions in run-down method sensitivity test, such as the relation between step size and stress number, the whole test number etc., were studied by computer simulation. The research results show that the whole test number should be more than 2 000 and the test number at every stress level should be more than 200 to perform the sensitivity distribution verification of initiating explosive devices. The practical example also shows that the research results have instructions on run-down method sensitivity test of initiating explosive devices.
