摘要

摘要: 对有氧化剂含铝炸药(RDX/AP/Al/粘合剂=20/43/25/12，下称含铝炸药)爆轰反应的点火增长模型进行研究。用VLW状态方程方法计算了含铝炸药爆轰产物JWL状态方程；用激光速度干涉仪（VISAR）测量炸药/窗口界面粒子速度和炸药驱动金属平板自由表面速度,对试验进行了数值模拟计算，拟合了含铝炸药的反应速率方程。研究结果表明，用VLW状态方程方法和炸药/窗口界面粒子速度确定JWL状态方程和反应速率方程可行，金属平板驱动试验的计算结果与试验结果吻合。

Abstract: This article reports Ignition and Growth equations of aluminized explosives containing oxidizer (RDX/AP/Al/HTPB=20/43/25/12). VLW EOS (equations of state) is applied to calculate the parameters of JWL EOS for this explosives. The free-surface velocities of the metal plate and the interface particle velocities between the explosive and sodium chloride window were recorded by the VISAR velocity interferometer. We have performed 3D numerical simulation for the particle velocities test to evaluate the parameters of the reactive rate EOS. The results show that the VLW EOS method and the explosion/widow interface velocity can be used to determine the JWL EOS and the reactive rate EOS. The results of metal plate acceleration test agree well with calculations.
