摘　　要：为研究飞片参数及冲击角度对冲击片雷管作用性能的影响,采用Solidworks和LS-DYNA软件对飞片剪切过程和不同角度冲击炸药的起爆效果进行了仿真,并通过仿真和试验验证飞片厚度和直径对其冲击速度的影响。结果表明:加速膛硬度越高,飞片成形状况越好;飞片最大速度与飞片直径、厚度呈负相关,但飞片厚度过小时易发生破碎现象;入射角度为0,30,60,90°的飞片冲击HNS药柱均能达到稳定爆轰,以0°入射角冲击时爆轰效果最佳。In order to study the effect of flyer parameters and impact angle on the action performance of slapper detonator,Solidworks and LS-DYNA were used to simulate the shear process of the flyer and the initiation effect of the explosive under different impact angles.And the influence of thickness and diameter of the flyer on its impact velocity was studied through simulation and test.The results show that the higher the hardness of the accelerator chamber,the better forming of the flyer;The maximum velocity of the flyer is negatively related to its diameter and thickness,but the flyer is easy to break when the thickness is too small;The HNS grain can achieve stable detonation when it is impacted by flyer with impact angle of 0°,30°,60°and 90°,and the detonation effect is the best when the impact angle is 0°.
