    摘要:

    为构建贴合实际需求的发射药烧蚀性能评价体系,设计半密闭爆发器烧蚀管实验,根据烧蚀管的几何尺寸及实验测量p-t曲线,建立了二维非稳态流动与传热模型,通过烧蚀管壁温的时空分布建立了瞬态烧蚀速率模型参数与烧蚀总量的关系。将半密闭爆发器烧蚀管实验的烧蚀量作为基准,采用粒子群算法对瞬态烧蚀速率模型参数进行了优化计算。结果表明:随着发射药燃气对烧蚀管冲刷时间增加,燃气与烧蚀管间的流固耦合界面温度有所降低,烧蚀管截面熔融深度的增速减缓;烧蚀管材料为45#钢,发射药为典型双基药(双芳-3)时,优化得到瞬态烧蚀速率的指前因子和表观活化能分别为0.3403 s-1和134.6 kJ·mol-1,此时损失函数值仅为3.0×10-6,可推广应用于身管武器平台的烧蚀状态计算。

    Abstract:

    A semi-closed bomb experiment was designed to construct a system for evaluating the erosion performance of propellant according to actual requirements. A transient numerical simulation model was established based on the geometric dimensions of the erosion tube and the measured p-t curve. The relationship between the transient erosion rate model parameters and the total mass loss of erosion tube was established through the space-time distribution of wall temperature of the erosion tube. Based on the mass loss of the semi-closed bomb experiment, the parameters of erosion reaction were optimized by particle swarm algorithm. The results showed that both the temperature of the interface between the propellant gas and the erosion tube wall and the growth rate of melting depth decreased with the increase of erosion time. The 45# steel and double base powder (Shuang-fang 3) were selected as the material sample and propellant sample. The optimized pre-factor and apparent activation energy values were 0.3403 s-1 and 134.6 kJ∙mol-1, respectively. At this time, the value of loss function was only 3.0×10-6. Thus, the transient erosion rate model is a promising tool to evaluate the erosion status of the barrel weapon.
