PBX-9502炸药爆轰约束三明治试验的数值模拟研究

Numerical Simulation of Detonation-confinement Sandwich Test of PBX-9502

利用形式简单单项爆轰反应速率模型对PB X-9502炸药爆轰约束三明治试验进行了数值模拟,模拟结果与A lsam等人爆轰约束三明治试验及相应爆轰冲击动力学(D SD)分析结果的比较表明,该单项爆轰反应速率模型可以用来准确地模拟爆轰约束三明治实验。在结构一定情况下,爆轰波阵面的曲率半径与约束材料有关。

Detonation-confinement Sandwich Test of PBX-9502 was simulated using a simple one-term reaction rate model.The simulation result was compared with results of tests and detonation shock dynamics（DSD） analysis,it can be found that the reaction rate model can be used to model Detonation-confinement Sandwich Test accurately.The results show that shock shape is dependent on the confined inert material under certain conditions.
