摘要
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。
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.
