试验设计在爆炸网络可靠性研究中的应用

Applications of experimental design in study of explosive network's reliability

为了设计和评价爆炸网络的可靠性,研究了影响爆炸网络可靠性的主要因素与可靠性特征量之间的定量关系。通过正交试验和均匀试验方法,首先对23个可能的影响因素建立正交试验分析,筛选出7个影响爆速的主要因素;然后基于主要影响因素构造有效的均匀试验,对试验结果进行回归分析,得到主要因素的取值与爆速间的定量模型。

Explosive networks are the key components to the initiations of aimed warheads and shaped charge warheads, which become the important way for the logicalization of ammunition detonating system. For designing and evaluating the reliability of an explosive network, it is important to find out the quantitative relationship between the reliability characteristic quantities and the major factors affecting the reliability. The quantitative models between the detonation velocity and its main factors were determined by the orthogonal and uniform experiments. First, the orthogonal experiment was carried out to select seven major factors from the twenty-three possible factors, and then these major factors were applied to create an effective uniform experiment to do regression analysis on the experi- mental results, finally the quantitative models between the detonation velocity and the main factors were figured out.
