尖拱类弹丸侵彻水沙介质理论分析与数值模拟
Based on water-entry dynamic and water-entry ballistic theories,the oblique water-entry process of disk ogive is simplified and a wetted correction factor is introduced in order to accord with the true water pile phenomena,and an oblique water-entry impact model coupled with ballistic and dynamic models are established.
以冲击体入水动力学和入水弹道学理论为基础,针对平头尖拱体入水冲击这个复杂物理现象,引入体现液面隆起现象的沾湿因子,用等效液面代替自由水平液面,建立了斜入水高速冲击的运动学和动力学冲击模型,其中动力学模型是根据平头尖拱体沾湿面的具体几何形状而建立。
