Study of fracture behavior of tungsten alloys under impact loading
Abstract
随着现代装甲结构的越来越复杂,尤其是具有较大倾斜角度的间隔目标的出现,钨合金长杆弹弹面临着新的渗透性能挑战。为了研究具有较大倾斜角度的间隔目标对具有较高长度直径比率的钨合金长杆弹丸的穿透性能的影响,这项研究对93W长杆弹射击渗透到斜距离距离的渗透进行了实验和数值模拟。通过使用高速摄像头,成功捕获了穿透目标后长杆弹丸的断裂形态。在水箱恢复实验中,在倾斜穿透后获得了钨合金杆弹的残留穿透器核心,进行了系统的扫描电子显微镜(SEM)分析。结果表明,长杆弹丸的断裂模式主要表现为钨粒的透射骨折。此外,确定了93W的JC组成型参数,并通过实验和模拟揭示了穿透多层间距靶标的长杆弹丸的固有定律。该研究发现,长杆弹丸的作用机理穿透了倾斜角度的间距靶标的是弹道挠度和长杆弹丸的断裂。通过更改长杆弹丸的常规“薄薄薄”结构,并实施措施,例如添加鼻子弹药的块和前凹陷的凹槽,针对倾斜距离目标的渗透有效性可以显着增强。
