可变形小口径枪弹的侵彻特性研究

为提高子弹的杀伤性，在标准小口径枪弹的基础上进行了新弹型的设计；利用LS-DYNA软件对开花弹和标准弹入水过程进行数值模拟，得到了两种不同弹型的头部变形图像和他们的速度衰减曲线、位移曲线以及相对动能曲线；最后进行了开花弹侵彻水介质的试验研究。结果表明：开花弹头部变形更大，呈花瓣状，且在低侵彻性和高杀伤性方面均优于标准弹。

Study on Warhead Deformation and Penetration Characteristics of a New Type of Bullet

In order to improve the bullet destruction,the design of the new type of bullet based on the standard small bore bullet was proposed. The numerical simulation of the process of water penetration about shrapnel standard projectile was performed using LS-DYNA,and we got two different bullet head deformation image and obtained their velocity attenuation curve,displacement curve and relative kinetic curve. Finally,the experimental study on the penetration of water about the shrapnel was provided. The results show that the warhead of the shrapnel has greater deformation than the standard projectile,and likes flower petal and is better than standard ammunition in the low penetration and high destruction.
