摘　　要：采用冲击波碰撞理论对环形传爆药柱中心线处冲击波碰撞类型进行了理论分析,对不同类型的冲击波碰撞给出了碰撞压力理论计算公式,得出了环形传爆药柱高径比和碰撞压力的关系曲线.计算表明,当环形传爆药柱高径比为0.5时,碰撞压力最大.与此同时,通过实验测试了环形传爆药柱在高径比为0.3,0.4,0.5,0.6和0.7时冲击波碰撞压力,实验结果表明在高径比为0.5时,碰撞压力最大,故实验得出的变化规律和理论计算结果变化规律一致.The collision style of shock wave in the center line of annular booster pellet was analysed through shock wave collision theory.The calculation formulas of different shock wave collision were provided.The relationship curve between the ratio of the height to diameter and the collision pressure was obtained.The theoretical calculation result showed that the collision pressure is the largest when the ratio of height to diameter of annular booster pellet is 0.5.The collision pressure of the annular booster pellet was experimentally tested when the ratio of the height to diameter was 0.3,0.4,0.5,0.6and 0.7.The experiment result also shows that the collision pressure is the largest when the ratio of height to diameter of annular booster pellet is 0.5.The variation tendency of the experiment result is well agreed with that of the calculation result.
