| 摘 要： | 应用AUTODYN-2D程序对卵形弹丸侵彻混凝土靶板进行数值仿真,以实验为依据,确定了合理的计算参数。针对不同预制孔孔径大小,进行了一系列关于弹丸侵彻带有预制孔混凝土靶板的数值实验。对Teland侵彻带有预制孔混凝土靶板理论中靶体阻力参数进行重新定义。通过与仿真结果的对比,发现改进的Teland理论能够对侵彻深度进行很好的预测。

| Abstract: | The concrete target penetrated by the ogive-nose projectile is numerically simulated with the AUTODYN code,and the parameters of the calculation are determined based on the experiment results.A series of numerical simulations of the concrete target with different size predrilled cavities penetrated by the projectile are developed.The target resistance of the concrete target in Teland's theory is redefined.By comparison with the numerical simulation results,it shows that the modified Teland's theory could we... |
