摘要

摘要: 固液混合装药物理参数是影响装药安全性的主要因素之一，利用混合炸药计算物理参数的方法，计算了几种典型配比装药的物理参数，根据能量守恒方程对不同物理参数的装药进行数值模拟。计算得到：在温度载荷相同的条件下，不同的物理参数对其温度响应有较大的差别，说明分析固液混合装药安全性时，应考虑装药不同比例对其安全性的影响，才能真实反应热点能量演化过程，为分析固液混合装药的安全性提供一定的理论依据。

Abstract: The physical parameter of the solid-liquid mixed charge is one of the main factors of the charge safety. Several typical ratios of composite charges were calculated by applying the calculation method of composite explosive physical parameter, and the different physical parameters of charge were numerically simulated based on the energy conservation equation. According to calculations, the temperature response with the different physical parameters has obvious differences at the same temperature load. Further analysis showed that the influence of different parameters of solid-liquid mixed charge on safety should be considered enough in order to truly explain the process of hot spot energy evolution, which provided theoretical basis for anglicizing solid-liquid mixed charge safety.
