球形和等长径圆柱装药在爆炸近区内载荷差异的实验研究
Blast loading difference between spherical charge and cylindrical charge with length equal to diameter at small scaled distances
摘要
Abstract
The pressure at the inner wall of the explosion vessel was measured by using the pressure bar method to investigate the influences of the charge shape on the blast loading in the field near the explosive source.The experimental results display that the maximum ratio of the peak and impulse of the reflected loading in the radial direction induced by the cylindrical charge with the length equal to its diameter to that induced by an equivalent spherical charge is larger than two.Numerical results,obtained by the numerical model which is validated by the experimental results,reveal the differences of hydrostatic pressure,density,particle velocity of blast loading between the two charges and the changes of the differences over the scaled distance from the blast center.关键词
