火炮零部件设计计算绘图一体化研究

Study on Integrated Design of Gun Components

分析了火炮ＣＡＤ发展现状，探讨了在火炮设计过程中，通过在Ｉ－ＤＥＡＳ软件上进行二次开发，建立零部件的三维参数化模型，根据设计计算程序的输出自动实现零部件不同结构类型三维实体图的输出的问题，提出了火炮零部件设计、计算、绘图一体化方案。详细介绍了方案中各组成部分的功能及实现方法，结合身管设计实例介绍了整个方案的设计思想。该方案的提出将进一步提高火炮设计的效率和质量，为实现火炮总体结构的参数化、系列化和优化设计打下基础。

This paper introduces the development of Gun CAD,discusses how to establish three dimensional parametric model and automatically realize solid drawing output of different structure type of gun components, according to design and computing results during the structure design of gun by further development in I DEAS software,proposes scheme on integrated design of gun component,including designing,computing and drawing.The implementation of the scheme is introduced in detail.The design idea is illustrated by a design process of barrel.This scheme is designed to further improve design quality and efficiency and lay foundation for parameterization,serialization and optimization of gun design.
