摘要 在关于二维定常爆轰边侧条件的理论分析中引入无量纲参数г来描述约束效应。基于阵面形状控制方程,给出了从理论上获取直径效应关系和熄爆直径的方法。通过拟合关于阵面形状的实验数据,确定了凝聚炸药PBXW-115的本构参数。直径效应和熄爆直径的理论计算结果与实验结果相吻合。 A dimensionless parameter describing the confinement effect is introduced in the theoretical analysis on the lateral conditions of the two-dimensional steady detonation of condensed explosives. Based on the differential equation governing the shape of detonation front, theoretical approaches leading to the diameter effect and the failure diameter are given. The constitutional parameters of the explosive PBXW - 115 are derived through fitting the experimental data of the front shape. The diameter effect, failure diameter and critical detonation velocity theoretically obtained are in good agreement with experimental results.
