摘　　要：通过对可燃药筒燃速公式的研究表明，由于药筒结构差异较大，若利用统一的整段模拟的燃速公式，误差较大；而对其分段处理并采用合适的拟合公式，效果很好，以此计算必将提高可燃药筒装药膛内数值模拟的精度。On the basis of theoretical and experimental result of closed bomb, the burning rate formula of combustible case is studied. Because of the large difference among different cases, the error will be large if we adopt the united burning rate formula for a whole combustion process. However, the effect will be good when we use the proper burning rate formula by segmented functions. In this way, we can improve the accurancy of numerical simulation about firing process. This will provide a reference for ballistic design of charge with combustible case.
