摘要
为了研究Q235钢多层板的抗侵彻性能,进行了直径为9.45 mm的钨合金球形破片侵彻7.2 mm和(3.6+3.6)mm厚Q235钢双层板试验,获得了相应的弹道极限。在此基础上,建立数值仿真模型,研究了钨合金球侵彻接触式等厚3层、4层、5层、6层板的弹道极限。通过量纲分析方法,分析了分层数对靶板弹道极限的影响。结果表明:对于球形破片,总厚度为7.2 mm的等厚双层板的抗侵彻性能高于单层板;当分层数大于2时,接触式多层等厚靶板的弹道极限随着层数的增加而减小,即分层数越多,靶板的抗侵彻性能越低,通过量纲分析方法得到了靶板分层数与破片弹道极限的关系。研究结果可为未来装甲防护设计提供一定的参考。
In order to study the anti-penetration performance of Q235 steel multi-layer plate,we carried out a 9.45 mm spherical fragment of tungsten alloy to penetrate the 7.2 mm and(3.6+3.6)mm Q235 steel double-layer plates,and obtained the corresponding ballistic limits.On this basis,we established a numerical simulation model to study the ballistic limits of the laminated contact plates with three,four,five,and six layers of equal thickness penetrated by the tungsten ball.Through the dimensional method,we analyzed the effect of the number of layers on the ballistic limit of the target.The results show that for spherical fragments,the anti-penetration performance of the double-layer plate with a total thickness of 7.2 mm is higher than that of the single-layer plate;when the number of layers is greater than 2,the ballistic limit of the multi-layer target decreases with the increase of the number of layers.The relationship between the number of layers of the target and the ballistic limit of the fragment is obtained by the dimensional method.The results can provide a guidance for the design of armor protection in the future.
