摘　　要：在Jacobs-Roslund准则分析基础上,对不同参数射弹冲击引爆带壳炸药阈值速度进行了数值模拟,获取了多个引爆临界速度关系曲线;建立了包含射弹直径、头部形状及材料等参数的引爆临界条件经验表达式,计算结果与已有的试验结果吻合较好.利用该式能较准确地计算射弹冲击引爆带壳炸药临界条件.Based on the analysis of Jacobs-Roslund formula, the threshold velocity of shelled explosive initiated by projectiles with different parameters, was simulated. Some curves of initiation threshold velocity were obtained. An experiential formula was established. The formula includes several parameters which are diameter, nose shape and material of projectile. The calculation result of the formula coincides with that of experiment well. The formula can be used to calculate the critical condition of shelled explosive initiated by projectiles.
