摘要

为了测定钛-三铝化钛（Ti/Al3Ti）层合复合材料在钨合金球形碎片作用下的弹道极限速度，采用一种12.7 mm弹道枪加载系统，对不同厚度的钛/Al3Ti层合复合目标进行了垂直冲击试验。得到了Ti/Al3Ti复合材料的弹道极限速度与靶区密度之间的关系。随着面积密度的增加，靶板吸收的弹道极限速度和弹道能量也增加。基于量纲分析和相似理论，研究了钨合金球形破片对不同厚度Ti/Al3Ti层合复合材料靶的侵彻模拟规律，得到了弹道极限速度的经验公式。研究结果对轻型装甲防护结构的优化设计具有重要的应用价值。

Ballistic limit velocity of tungsten alloy spherical fragment penetrating Ti/Al3Ti-laminated composite target plates

To determine the ballistic limit velocity of titanium–titanium tri-aluminide (Ti/Al3Ti)-laminated composites under the action of tungsten alloy spherical fragments, a type of 12.7 mm ballistic gun loading system was used to test the tungsten alloy spherical fragments vertically impacting the Ti/Al3Ti-laminated composite targets with different thickness. The relationship between the ballistic limit velocity and the target area density of the Ti/Al3Ti-laminated composite was obtained. As the area density increased, the ballistic limit velocity and the ballistic energy absorbed by the target plate also enhanced. Based on the dimensional analysis and similarity theory, a simulation law of tungsten alloy spherical fragments penetrating Ti/Al3Ti-laminated composite targets with different thickness was studied and an empirical formula for the ballistic limit velocity was obtained. The research results had an important application value for the optimal design of the light armor protection structure.
