摘　　要：为实现战斗部离散化模型的快速生成,提出将战斗部结构分解为5类特征,用轴截面母线特征点参数化描述特征形状,自主构建相应的以代数方法为主的网格生成算法并用C++语言编制成程序,程序读取格式文件获取参数后即可快速自动生成适用于AUTODYN或LS-DYNA软件的离散化模型的网格文件。该程序作为战斗部离散化建模的专用程序在参数化建模的能力和效率上均优于TRUEGRID等通用建模软件。In order to implement fast grid generation on warhead, warhead＇ s structure was divided into 5 kinds of geometrical characteris- tics. Key points of generatrix in the section axis were chosen to depict the configuration of each characteristic. Corresponding algorithms and programs of grid generation were established. Those customized programs with C ＋＋ programming language can produce grid file ap- plied to AUTODYN or LS-DYNA automatically after getting parameters by reading formatted file, excelled to generic modeling software, TRUEGRID, for example, in modeling ability and modeling efficiency.
