摘要
为提高子弹的低侵彻性,设计了一种新弹型—开花弹。开展开花弹以不同速度侵彻明胶块的实验,研究弹体头部的变形情况,并利用侵彻深度验证了弹丸的低侵彻性能。研究结果表明:开花弹在撞击明胶块的过程中,其头部开裂程度与枪弹的撞击速度有关,且速度越高,弹头变形越大;弹头开裂成"花瓣状"可增大侵彻阻力,有效降低子弹的侵彻深度;开花弹在不同速度区间内均未穿透明胶块,证明该弹具有良好的低侵彻性能;提出了开花弹的运动模型,该模型可以较好地描述开花弹在明胶内的运动过程。
In order to improve the bullet destruction, the design of the new type of bullet—shrapnel, which is based on the standard small bore bullet is proposed. The experiment of gelatin penetrated by shrapnel is performed to study the deformation of projectile's head at different speed range and through the penetration depth of the projectile. The low penetration performance of the projectile is verified in this study. The results show that the degree of deformation of the projectile's head is related to the speed, the higher the speed, the greater the warhead deformation. Warhead cracking into the "petal" can effectively reduce the bullet velocity, and increase the penetration resistance. The shrapnel does not perforate the gelatin at all the testing speeds, which proved that the projectile has good low penetration performance. A motion model of shrapnel is proposed, and the model can describe the dynamic process of shrapnel better.
