基于三维的起重葫芦CAD应用开发研究

On the development of 3-D CAD system of crane tool and its application

起重葫芦产品 CAD系统的研究开发在国内属于空白领域。文章提出了 CA D系统的开发原则和总体框架结构设计形式 ,论述了 CAD系统的方案设计、分析计算、三维零部件造型和模拟装配干涉校验等各个功能模块的内容 .基于以上内容完成了 CAD系统的开发。 CAD系统在行业的应用中取得了较好的技术经济效益。

This paper introduces the development of CAD system of crane tool, which is presently a new research area in China. The development principles and the overall structure of the CAD system are presented.The emphasis is laid on the analysis of the function modules,including the scheme design module,analysis and calulation module,modeling module of 3 D components, simulative fitting module, design module of dies and design moudule of 2 D drawing.The developed 3 D CAD system of crane tool has been applied in an enterprise with good technical and economical results.
