穿爆弹侵彻多层间隔混凝土靶数值模拟分析

Numerical Simulation Analysis of Multi-layered Concrete Target

为利用终态侵深公式得到穿爆弹侵彻多层间隔混凝土靶每层靶后的剩余速度,借鉴Young公式的思路,提出了一种基于非线性加速度模型计算剩余速度的方法。利用该方法分别计算了穿爆弹在垂直及20°入射角条件下侵彻三层间隔混凝土薄靶板的剩余速度,然后进行了数值模拟,并对比了前人的求解方法。结果表明,利用该方法所得结果与数值模拟结果吻合,验证了该方法的合理性,对工程防护及武器设计有一定的参考。

In order to obtain the residual velocity of the missile by penetrating the multi-layer spacing concrete target by using the ultimate invasions formula,a method based on the nonlinear acceleration model is proposed by reading the literature and drawing on the Young formula,The method of calculating the remaining speed. By using this method,the residual velocity of the three-layer concrete thin-bed target penetrated under the condition of vertical and incident angle is calculated,and then the numerical simulation is carried out and compared with the predecessor ’s solution method. The results show that the method is consistent with the numerical simulation results,which verifies the rationality of the method and has some reference for engineering protection and weapon design.
