摘要
为研究球形空腔内部爆炸条件下空腔壁面反射超压的变化规律,对不同半径球形空腔内爆炸进行了数值模拟分析。结果表明,采用1 mm的网格尺寸模拟计算得到的球形空腔内壁面荷载更加接近试验值。随着空腔半径与装药半径之比逐渐增大,空腔内壁面荷载的峰值逐渐减小,且脉宽逐渐增大。
In order to study the variation law of the reflected overpressure on the cavity wall,the blast in the spherical cavity with different radius was numerically simulated.The results indicate that simulation using a 1 mm mesh size provides a closer approximation to the test value for the load on the wall in the spherical cavity.As the ratio of cavity radius to charge radius increases gradually,there is a decrease in the peak of the load on the wall and an increase in the width of the pulse gradually.
