基于反向撞击法的JB-9014炸药Hugoniot关系测量
|
摘要
为了获得JB-9014未反应炸药的Hugoniot关系,在火炮加载平台上利用反向撞击技术对JB-9014炸药进行一维平面冲击实验。将JB-9014炸药样品作为飞片安装于弹托前表面,将镀膜氟化锂窗口作为装置靶。利用火炮加速弹托,使炸药样品以一定速度撞击镀膜氟化锂窗口,通过光子多普勒测速仪(photonic Doppler velocimetry,PDV)测量炸药样品击靶速度以及炸药/镀膜氟化锂窗口界面粒子速度。最终根据冲击波阵面守恒关系计算获得了JB-9014炸药冲击Hugoniot数据,采用正交回归直线拟合得到了炸药样品在3.1～8.2 GPa压力范围内的冲击Hugoniot关系:D_s=2.417+2.140u_s (D_s和u_s的单位均为km/s)。结果表明:该方法测试精度较高,响应时间快(小于5 ns),同时该方法可以对炸药的反应情况进行检测,便于判断实验是否测得真实的未反应炸药冲击Hugoniot数据。
In order to obtain the Hugoniot relation of unreacted JB-9014 explosive, one-dimensional plane impact experiments of the JB-9014 explosive were completed on a gun by using the reverse-impact method.The JB-9014 explosive sample was mounted on the front surface of the sabot as a flyer. The LiF window was taken as a device target. The sabot was accelerated to a certain speed by the gun and then the explosive sample impacted the LiF window. The impact velocity of the flyer and the particle velocity at the sample/window interface were measured by a photonic Doppler velocimetry(PDV). The Hugoniot data was obtained according to the conservation of the shock. The Hugoniot relationship of the JB-9014 explosive sample within the pressure range of 3.1-8.2 GPa was established by using the least square method. The results show that reverse-impact method has the characteristics of high accuracy and fast response time(<5 ns). In addition, the reverse-impact method can be used to detect the reaction degree of the JB-9014 explosive, which can be applied to judge whether the real Hugoniot data of the unreacted explosive is measured in the experiment.
