Abstract

The article investigated the process of penetration of an aluminum plate by a steel ball at speeds from 600 to 1000 m/s. A numerical simulation of the impact of the ball was carried out and compared with the results of experiments in which the ball was accelerated using a powder accelerator. Numerical models were developed using the explicit finite element method in LS-DYNA software. The influence of material properties and model parameters on the penetration process is analyzed. A good agreement between numerical and experimental results has been achieved.

钢球撞击铝板 D16 的模拟及与实验的比较

摘要本文研究了钢球以 600 至 1000 米/秒的速度穿透铝板的过程。对钢球的冲击过程进行了数值模拟，并与使用粉末加速器加速钢球的实验结果进行了比较。数值模型是使用 LS-DYNA 软件中的显式有限元法建立的。分析了材料特性和模型参数对穿透过程的影响。数值结果与实验结果之间取得了良好的一致性。
