摘要
研究了ＰＢＸ９４０４ 炸药在高幅值冲击波加载下的化学反应速率方程。将所得高压反应速率方程与Ｊｏｈｎｓｏｎ 等的经验热点模型的低压项结合，得到ＰＢＸ９４０４ 炸药的冲击波起爆反应速率模型。利用一维特征线程序模拟该炸药的冲击波起爆过程和爆轰波传播过程。
The chemical reaction rate of PBX 9404 for high shock loading has been developed in this paper.This high pressure reaction rate combined with the low pressure term of Johnson ,s empirical hot spot rate result in a new shock initiation model for heterogeneous PBX 9404 explosive.According to this model,we have simulated the process of shock initiation and detonation wave propagation of PBX 9404 by means of a one dimensional characteristic code.
