解析方法与数值模拟相结合求解炸药在容器内部爆炸产生的壁面载荷

本文采用总变差递减（TVD）数值方法与强爆炸解析解相结合的手段，求解了炸药在爆炸容器内部产生的作用载荷。计算结果与实验值在几个典型位置进行了比较，二者有良好的符合。与单纯的数值方法相比，本文所探索的方法能有效地克服对称轴附近的数值振荡，不失为确定爆炸载荷的一种新途径。

Combining Analytical Method with Numerical Simulation to Obtain Blast Load on Chamber Wall Produced by an Explosive Charge

The method combining numerical simulation with analytical solution of strong explosion was employed to determine blast load on the inner wall of an explosive chamber produced by a concentrated charge with different weight. The calculated results were compared with those of experiments at several typical position on chambers and showed a good agreement. The approach can eliminate the numerical oscillation near the symmetric center of chambers and was effective to determine the blast load.
