摘要:本文对某型针刺雷管的两个批次分别进行了完全步进法及升降法感度试验。根据试验数据,计算同一刺激量下采用步进法与升降法得到的产品发火率,由Boltzmann模型拟合得到p——x曲线。根据曲线可知,在评价火工品安全性与可靠性时,升降法估计值比步进法偏乐观;当评估0.999响应点时,升降法较步进法对应的刺激量平均低约20%。
Abstract:Using the sensitivity test data of the stab detonator compares the complete run-down method and Bruceton up-and-down method. The results show that Bruceton up-and-down method is more optimistic than the complete run-down method when the 0.999 responses is evaluated, and the stimulated value obtained by Bruceton up-and-down method is 20% lower than that obtained by the complete run-down method.
