摘要
本文介绍了一个适合于中小港口用的起重机金属结构CAD系统。它包括起重臂、人字架和转台结构的常规设计计算软件、优化设计软件、有限元分析软件和计算机绘图子系统四个部分。CAD系统采用全汉化菜单技术,实现人机交互;采用参教绘图,实现设计计算和绘图一体化;采用数据库技术,实现系统内数据共享。
This paper presents a microcomputer CAD system which consists ofa set of subsystems, i.e., the traditional design software, the structure optimizationprogram, the finite method package, and the parameter drafting software. Thissystem is developed particularly for designing the structure of jib cranes. The systemis an interactive, integrated one with Chinese menus, being able to do designing,calculating, optimizing, as well as automatic drawing. A database for steet sections isalso given to meet the needs of automatic index in the running of the CAD system.
