| 摘 要： | 固体炸药样品的装药尺寸对其冲击起爆的特性有着比较明显的影响，本文利用非线性有限元方法模拟计算了JO－9159炸药冲击起爆过程，分析了炸药冲击起爆过程的尺寸效应，结果表明，在一定范围内，JO－9159炸药的起爆力阈值随装直径和装药长度的增大而减小。

| Abstract: | The dimension of solid explosives plays an important role in the characteristic of the shock to detonation transition (SDT). The nonlinear finite element code was used to calculate and analysis the dimensional effect of the SDT of JO 9159. The results show that the initiation pressure threshold of JO 9159 decreases along with increasing of the diameter and thickness of the explosives. |
