摘　　要：利用数值模拟研究不同聚能穴直径下异形传爆药柱的起爆能力,选择模拟中最佳的尺寸进行实验研究。结果表明:保持下底直径和体积不变,异形传爆药柱的起爆能力随聚能穴直径的增大先提高后降低;异形传爆药柱起爆能力好于圆柱形。The initiation capacities of special booster pellets with different energy cavity diameter were studied by numerical simulation, and the experiment was carried out with the best simulated diameter. The results show that the initiation capacity of special booster pellet increases at first and then decreases with diameter of energy cavity increasing for constant diameter and volume of lower bottom. The initiation capacity of special booster pellet is better than that of cylindrical booster pellet.
