摘要本文介绍了杀伤爆破式战斗部辅助设计软件的总体思路、框架结构,并编程实现。该软件包括弹药建模、特征参数计算和破片场计算三大模块。
在弹药建模中,将弹丸整体划分为多个规则的基本体,通过这些基本体的组合得到完整的弹丸,实现建模过程。建模完成后,程序完成组成弹丸的各基本体特征参数计算,然后再根据组成弹丸整体的各个基本体的位置,计算出弹丸整体的特征参数。破片场计算模型中,对弹丸整体进行微元化处理,计算各个单元的破片质量、初速和飞散角,然后分析各个微元对弹丸整体破片的贡献比例,通过划分质量区间、飞散角区间的方法,得出破片数据的分配表。32160
该软件为弹药设计人员提供了一套高效、便捷的设计工具,大大提高了设计效率。

Title Design software for explosive warhead aided design
Abstract
In this paper, the overall thinking, frame structure and programming of the assistant design software of the explosive warhead are established. The software includes ammunition modeling, parameter calculation and characteristic fragment field calculation.
In the modeling of ammunition, the whole ammunition is pided into many regular basic bodies. The integrated projectile is obtained through the combination of the basic body, and the process of modeling is realized. After the completion of the modeling, the parameters of the basic body of the projectile are calculated, then the characteristic parameters of the projectile are calculated based on the positions of the regular basic bodies. In the fragment field calculation model, the projectile is micro processing. Then calculate mass, initial velocity and scattering angle of each unit. Using the method of piding the quality and scattering angle sections, the distribution of fragment data table can be got before analyzing the proportion that each element of the overall contribute to the whole projectile.
The design software of the explosive warhead aided design software is an effective and convenient design tool for the ammunition designers, which greatly improves the design efficiency.
