柱形破片对多层间隙靶侵彻试验研究

Experimental Investigation on Cylindrical Fragments Penetrating into Multi-spaced Targets

对钨合金柱形破片侵彻多层铝合金间隙靶板进行了试验研究,模拟预制破片弹中杀伤元对目标的侵彻特性。分析了破片质量、着靶速度对多层靶板侵彻能力的影响,获得了基础试验数据,并结合工程计算模型,拟合得到了靶板侵彻层数随破片质量、着靶速度的数学方程。该拟合方程可用于评估长径比为1且正侵彻的钨柱形破片的侵彻能力,对预制破片弹的破片选择提供实用参考。

Multi-spaced targets of Aluminum alloy penetrated by cylindrical tungsten fragments were experimentally investigated, which simulates the penetrating capability of fragments to target. The penetrating layer is analyzed with the variety of fragment mass and velocity. On the basis of experimental results, a simulating formula of was established. The forroula can be used to evaluate the normal penetrating ability of tungsten cylindrical fragment whose ratio of length to diameter is 1. Those studies provide practical reference for fragment warhead.
