摘要

摘要: 利用二级轻气炮开展了杆形钢弹在10马赫左右条件下对4种分层地质类材料靶体的超高速侵彻模型实验，重点研究了砂浆层位置和空气隔层对侵彻效应的影响。结果表明增加遮弹层与下部结构间的空气隔层、在整个结构顶部设置疏松砂浆层均可以在一定条件下加剧弹体破坏、减小结构层的侵彻深度，但同时会增加遮弹层的表面成坑效应。从减小结构层的侵彻深度出发，“软-硬-软-硬”的分层设计思路对抵抗超高速弹体侵彻是可行的。

Abstract: Model experiments of hypervelocity penetration of steel rods at about Mach 10 into four types of layered geological material targets were conducted with a two-stage light gas gun, and the effects of the mortar position and the air-layer set on penetration were emphasized. The results show that, under certain conditions, both adding an air layer between the shielding layer and the lower structure layer and setting a mortar layer at the upper surface of the whole structure can promote the projectiles broken, decrease the penetration depth into the structural layer, but in the mean time intensify the cratering effect of the shielding layer. For reducing the penetration depth of the structural layer, the soft-hard-soft-hard layering set is feasible to optimize the anti-penetration performance against hypervelocity projectiles, in which the first soft layer is the surface layer made of porous materials with low sound impedance, the first hard layer is the shielding layer made of materials with high strength and hardness, and the second soft layer is the distribution layer and the second hard layer is the structural layer.
