嵌入AutoCAD的连杆曲线图谱自动绘制系统的研发

Reaserch and development of Linkage curves diagram automatic drawing system imbed in AutoCAD

为掌握和研究连杆平面上各点的运动规律提供快速的可视化支持,建立了连杆空间上点的运动轨迹曲线,利用C++语言开发了一套连杆曲线图谱自动绘制和图谱库查询系统,并将其嵌入机械制图软件AutoCAD中,通过交互式操作传递参数,在AutoCAD平台上自动完成参数化连杆曲线图谱的绘制,使连杆曲线上点的运动规律更加形象、直观,提高了机构设计的效率。

In order to provide rapid visible support for controlling and studying the movement rule of point in linkage plane, movement track curves of points in linkage plane was established. Using C＋＋ language, a set of linkage curve diagram was drawn automatically and diagram database search system was developed, which was imbed in the mechanical drawing software AutoCAD. Parameters were passed by interactive operation, and parameterize linkage curves diagram were drawn automatically on the platform of AutoCAD, which make movement rule of points in linkage curve more visual and intuitionistic. These promote the efficiency of mechanism design as well.
