摘　　要：为了研究固液混合装药在发射过程的安全性,从固液混合装药的物理特性出发,考虑战斗部发射时装药与壳体的摩擦生热,在壳体和装药之间建立能量守恒方程,利用有限差分对其进行数值计算。计算得到,当战斗部转速为40 r.s-1时,燃料最高温度为542 K,结果表明:装药与壳体之间的摩擦是固液混合装药发射过程的主要危险源。Conservation equation of energy based on the physical property of solid-liquid mixed charge and the heat caused by the friction between shell and charge during launching,was established and calculated by finite difference method to analyze the launching safety of solid-liquid mixed charge. Results show that the maximum temperature of charge reach 542 K when the warhead rotation speed is 40 r · s^-1, and the warhead rotation is the main hazard source in the launch process of solid-liquid mixed charge.
