基于VBA的道岔自动配置软件开发方法研究

Railway turnout automatic configuration software through VBA

本文基于VBA对AutoCAD进行二次开发,研究道岔及岔后附带曲线的坐标计算方法,并设计程序可视化界面实现不同型号的道岔自动配置要求,使得在岔心位置确定条件下,根据具体的道岔型号及线间距等因素,可以自动准确计算道岔各部位,岔后附带曲线的位置信息并绘制道岔布置图。

This thesis was based on the re-development of AutoCAD via VBA, studied on the coordinate calculation method of turnout and the turnout curve. Visual interface was designed to achieve automatic conifguration of different types of turnouts. When the center position of the fork was under the conditions, it could be ensured the accurate calculation of the various parts depending on the type of the turnout and other factors, especially the turnout bifurcated incidental information and position of the curve plotted turnout layout.
