摘要
系统阐述了数值模拟技术这一新兴手段在钻地武器研制中的主要算法及应用 ,比较了算法之间的优缺点 ,介绍了当今流行的各种主要计算程序。作为算例 ,运用非线性动力有限元LS DYNA计算程序 ,对一个防空建筑在弹头侵彻下的动态响应及应力变化情况作了计算 ,图像形象显示了战斗部在侵彻过程中的形变及其速度、质量随时间的变化情况。
In this paper, the application and main algorithms of the new developing digital simulation technique are set forth in earth penetrator weapon development and their differences are compared. The digital simulation technique which utilizes the LS DYNA computation program computes the dynamitic response of some anti air construction under a bullet pressing and its vary stress, and its imaging displaies part visually the changes of velocity, mass and shape with in time. At the end of the article, the application of digital simulation technique in weapon design area is described.
