| 摘 要： | 为了研究高温环境对钝感炸药爆轰波波阵面曲率效应的影响,采用高速扫描照相技术及电探针测速技术获取了高温60℃环境下TATB基钝感炸药三种直径药柱爆轰波拟定态爆轰波形状及波速。结果表明,TATB基钝感炸药在高温60℃下的拟定态爆轰波波速随着炸药直径基本呈现线性增长趋势,且相同直径的高温结果均低于常温结果。三种直径TATB基钝感炸药在高温60℃下的拟定态波阵面形状较常温结果更为陡峭。采用遗传算法对三种直径炸药的实验结果进行拟合计算,获得了TATB基钝感炸药高温曲率效应D_n(κ)关系参数。采用DSD(Detonation Shock Dynamics)方法对三种直径炸药的爆轰波非理想传播过程进行了模拟,计算结果与实验结果吻合较好。

| Abstract: | To study the influence of high temperature on the front curvature rate effect for insensitive high explosives, steady-state detonation velocities and wave shapes were obtained for TATB Based Insensitive High Explosives(IHEs) with three different diameters at the temperature 60 ℃ by using high speed streak camera technique and electric foil velocimetry.Results show that steady-state detonation velocities increase almost linearly with the diameter of TATB based IHEs at the temperature 60 ℃.For each charge diameter, steady-state detonation waves propagated slower and the wave shapes become much curved as the initial temperature increases.The Dn(κ) parameters of TATB based IHEs at the temperature 60 ℃ were obtained numerically using the genetic arithmetic method for DSD.By using these Dn(κ) parameters, the detonation propagation behaviors of TATB based IHEs at the temperature 60 ℃ were simulated with the DSD model.The numerical results agree well with the experimental ones. |
