不同材料双层球缺罩侵彻特性的研究

采用数值模拟及钢靶侵彻试验两种方法研究了单层钛合金球缺罩、钛合金/铜、铝合金/铜双层球缺罩形成的3种杆式射流对45#钢锭靶板侵彻深度和开孔的问题。研究结果表明:不同材料的双层球缺罩形成的杆式射流对45#钢锭靶板的开孔孔径和侵彻深度大小均有直接影响,且钛合金/铜双层罩杆式射流破甲深度相对于铝合金/铜双层罩有一定提高,其开孔孔径明显增大。而单层钛合金药型罩杆式射流整体速度最大,开孔孔径较钛合金/铜、铝合金/铜双层罩杆式射流有明显提高,但破甲能力较低。研究结果对于武器战斗部设计具有一定的指导作用。

Penetration Characteristics of Double-layer Hemispherical Liner Made of Different Materials

In this paper, penetration depth and opening problems of 45# steel ingot target caused by three kinds of rod-shaped jet formed by the single-layer titanium alloy hemispherical liner, titanium alloy/copper and aluminum alloy/copper double-layer hemispherical liner were studied by numerical simulation and steel target penetration test.The results show that different types of rod-shaped jets have a direct influence on the aperture and penetration depth of the 45# steel ingot target plate.Penetration depth of titanium alloy/copper double-layer rod jet has a relative increase compared to alumi-num alloy/copper double-layer rod jet, and the aperture increases significantly.The whole velocity of the single layer titani-um is the largest, and the aperture is higher than that of titanium alloy/copper and aluminum alloy/copper double layer rod jet, but the armor capability is low.The results of this paper have a certain guidance on the design of weapon warhead.
