摘要
为了满足大型工程系统对组合型材的快速参数化设计要求,本文设计开发了一套针对组合型材的参数化绘图系统。系统在天喻参数化零件库的基础上,以其参数化和数据库技术做支撑,通过其参数化驱动的技术来绘制单个型材的截面图形,并通过一系列的变换矩阵对截面图形进行变换,以达到相互组合的目的;并根据组合后的图形数据,在特定的消隐算法的基础上,完成组合型材的水平与竖直方向的投影视图。文中分析了此系统的框架结构,并对所涉及到的关键技术,如型材的组合运算、方位视图的生成以及对型材视图的投影所涉及到的消隐算法进行了介绍,最后给出了此系统在某锅炉企业中的应用实例。
To meet the requirements of the large-scale engineering systems which need a parametric rapid design system for the combined structural sections.A system of parametric drawing for the combined structural sections has been designed and developed.The system based on the technology of the parametric design and the database of The Tianyu Part Library to draw a single structural section cross-section graph and transform the graph through a series of transformation matrices to get the combined graph.With a special blanking algorithm to support,the system achieves the projection view of the horizontal and vertical directions of the combined structural section by the combined graph＇s database.This paper analyzes the system＇s framework,and introduces the key technologies involved,such as the structural section of the combination,the location view of the structural section and the blanking algorithm of the projection view.An application example in a boiler enterprise is given.
