| 摘 要： | 运用ANSYS/LS-DYNA软件,分别对头部形状为30°锥角,60°锥角和抛物线形的钻地弹斜侵彻土壤的过程进行数值模拟,得到了运动轨迹图,弹丸侵彻加速度过载曲线,以及弹丸侵彻深度曲线;分析了过载曲线的特征,通过比较,总结出了钻地弹的头部形状对其斜侵彻土壤时运动规律和运动特性的影响,为钻地弹设计提供了参考依据。

| Abstract: | The numerical Simulation of the Earth Penetrating Shell into soil was made by using ANSYS / LS-DYNA software.The nose shape of the Earth Penetrating Shell were respectively 30 ° cone angle,60 ° cone angle and the parabola-shaped.The movement rules,the deceleration-time curves,and the depth-time curves were got in the process.The characteristics of curves were analysised.By comparison,the effects of the nose shape for the process of the Earth Penetrating Shell into soil were summed up.The curves are soffered as the reference and basis for the Earth Penetrating Shell design. |
