摘要/Abstract

摘要： 基于Jones-Wilkins-Lee(JWL)状态方程，利用三波理论和Whitham方法对凝聚炸药爆轰波相互作用后发生的正规斜反射和马赫反射进行了理论分析。推导了基于JWL状态方程的爆轰波正规斜反射和马赫反射压力及马赫杆高度的计算模型；提出了改进Whitham方法中的慢变函数k(ξ) 的理论计算方法。使用PBX 9501炸药和JH-2炸药的试验结果对计算模型进行验证，理论计算结果与试验结果吻合较好。试验结果表明，基于JWL状态方程建立的理论计算模型，对于凝聚炸药爆轰波相互作用后发生的正规斜反射和马赫反射，能够较准确地描述其爆轰参数分布和传播规律。

Abstract: The regular oblique reflection and Mach reflection of detonation waves in condensed explosive after their interaction are investigated using the three-wave theory and the Whitham's method on the basis of Jones-Wilkins-Lee (JWL) equation of state (EOS). The JWL EOS-based calculation model of regular oblique reflection, reflection pressure and Mach stem height is derived. A theoretical calculation method is proposed for the slowly changed function k(ξ) in the modified Whitham's method. The calculation model was verified with the experimental data of PBX 9501 and JH-2 explosives. The calculated results are in good agreement with the experimental results, which means that the calculation model based on JWL EOS can be used accurately to predict the detonation parameters distribution and propagation process of regular oblique reflection and Mach reflection.
