摘　　要：现代战争对弹体在侵彻靶体过程中运动轨迹的准确性和可预测性提出了较高的要求，以试验为主的传统方法和纯粹的数值模拟方法均不能对预测弹体在深层侵彻过程中的运动与相关设计提供有效的方法。本文详细阐述了基于弹靶分离方法程序的发展现状，进而解释了弹体与靶体介质分离的方法，描述了建立弹体在靶体介质中运动、变形及磨损的理论框架和开发方案。建立了一种包含经验公式、理论方法及数值模拟的分析方法，从而能够对弹体的深层侵彻过程进行快捷、有效及准确的预测，为弹体设计及防护工程设计提供有效的工具，为军事打击效果评估提供实时数据。The demand of modern war on the accuracy and predictability of the projectile trajectory in the process of penetrating the target is high. The traditional method of experiments and sheer simulation can not be effective during the deep penetration of the projectile. In this paper, the development of the procedures based on the pro-jectile and target separation is described in detail. With the projectile and target separation, the theoretical frame- work and exploitative programs of the projectile＇s movement, deformation and erosion in the target are estab-lished. An analysis method combining empirical formula, theoretical methods and numerical simulation is developed, which makes the fast, efficient and accurate prediction of the projectile＇s deep penetration possible and provides an effective tool for projectile design and protection engineering design and the timely data of the mil- itary battle damage assessment.
