摘　　要：研究了温度对发射药热自燃、分解放热速率以及分解反应热的影响 .建立了发射药热自燃的物理模型以及导热微分方程 ,利用数值模拟的方法计算了不同温度下发射药的自燃时间 ,并与实验结果进行了比较 ,最后对计算结果进行了分析与讨论 ,计算结果与实验结果基本相符 。The influence of temperature on thermal self ignition, heat release rate and reaction heat for propellant decomposition is studied. The physical model and differential equations of heat conduction for propellant are established. Based on the numerical calculation, the self ignition time of propellant in different temperatures are calculated. The calculation results are discussed and compared with the experiments. The calculation results are in accordance with that of experiments and the realiable foundation is provided for the calculation to self ignition of propellant.
