摘　　要：为研究火药的实际燃烧规律,建立了定容条件下火药燃烧的修正数学模型,分析了火药实际弧厚的分布及变化、点火不同步和燃速系数变化等因素对火药实际燃烧规律的影响。在此基础上,用考虑综合因素的修正数学模型对定容条件下火药的实际燃烧过程进行了模拟,计算值与实验结果具有较好的一致性,说明修正模型所建立的假设及处理方案是合理的。The correctional mathematical model of propellant combustion on the constant volume condition is established for studying propellant actual combustion law. The influence of distribution and variety of web thickness, non-synchronous ignition, burning rate coefficient changing, etc. on propellant actual combustion law were analyzed. On the basis of these analyses, the propellant actual combustion process was simulated by the correctional mathematical model including comprehensive factors. The calculated results have better consistency with experimental results ,showing that the hypothesis and scheme established by correctional mathematical model is reasonable.
