摘要
文中应用缩尺模型技术(相似定律)研究钻地弹侵彻混凝土的问题,在理论上阐明了钻地弹侵彻混凝土模型的相似比。以此作为选择缩尺模型的问题依据,并用大型有限元分析软件LS-DYNA进行数值模拟,证明了其合理性。
The problem of penetrator biting into concrete target is studied by technology of scale model （similarity law） in the paper. Similarity ratio of penetrator into concrete target is represented in the theory, which as laws by selecting scale model. It is reasonable by using numerical simulation of large finite software LS-DYNA.
