不同头部形状弹体高速侵彻混凝土试验研究

为研究高速撞击条件下弹体侵彻能力、弹体侵彻极限速度、弹体质量损失等问题，在高速弹道炮上开展了不同头部形状弹体对混凝土靶体高速正侵彻的模型试验，试验最高弹速达到了1 420 m/s，获得了侵彻深度与侵彻速度之间的关系. 结果表明，随着弹体速度的增加，弹道的稳定性逐渐变差，弹体头部侵蚀加重，当弹体初速度大于弹体极限速度时，弹体出现弯曲破坏，侵彻深度下降；不同的头部形状对弹体弯曲变形、弹体头部侵蚀、弹体侵彻深度有着很明显的影响.

Study on Different Nose Profile Projectiles Penetration into Concrete Targets with High-Velocity

In order to study the penetration performance, penetration speed limit and mass loss of the projectile under the high-speed impact conditions, the normal high-speed penetration model tests were carried out through the projectiles with the different head shapes on the high-speed ballistic gun. The maximum speed of projectile reached 1 420 m/s. Through the test, the relationship between the penetration depth and penetration velocity was obtained. The results show that with the increase projectile velocity, trajectory stability is degraded and projectile head erosion aggravated. When the projectiles initial velocity is greater than the speed limit, projectiles occur bending failure, and the penetration depth declines. The head shape of projectile has obvious effects on the bending, head erosion and penetration depth.
