摘　　要：榴弹方案设计可以根据战术技术指标要求 ,通过参数化实体建模技术自动完成 ,榴弹强度计算和零、部件结构设计需进行有限元计算。本文结合榴弹设计特点 ,利用C语言开发了一个数据生成模块 ,能根据榴弹设计方案 ,自动完成弹体剖分并形成有限元软件计算所需的数据文件 ,使强度计算和方案设计完整结合起来 。In accordance with the demands of a design, through the modeling of geometrical parameters, automatic design of shrapnel can be performed, and the strength calculation and design of parts finished in FEM. Based on the characteristics of design of the shrapnel, development of the special subroutine in C language is performed automatically, and the mesh and data file for FEM computation provided. The design of profile and strength analysis of the shrapnel are integrated to guarantee the qualities of design and to increase efficieny.
