炸药反应率的理论分析和数值计算

Theoretical Analysis and Numerical Computation for Explosive Reaction Rate

依据爆轰建立过程的唯一迹线原理,结合三个守恒方程及状态方程,推导了炸药在冲击载荷下起爆的一系列关系式及计算公式,编制了计算炸药起爆率的程序。计算分析中,采用了JWL状态方程描述未反应炸药及其爆轰产物,应用梯度迭代法求解了非线性方程组,获得了合理的炸药起爆率数据。研究表明,唯一迹线原理是描述炸药爆轰建立过程的一种有效方法。

Based on the unique locus principle of detonation process, in combination with three conservation equations and equation of state, a series of relations and calculation fomula are derived for explosive initiation under impact load. The computing code is written for explosive initiation rate. In the calculation analysis, JWL of equation of state is applied to describe unreacted explosive and detonation products. The gradient iteration method is applied to resolve non - linear equations, and the explosive initiation rate data are obtained. It is shown, the unique locus principle is effective for establishing explosive detonation process.
