城轨线路道岔模型生成算法研究

Research on generation algorithm for switch model of Urban Transit

通过对轨道线路中单开道岔模型的结构和线型进行分析,总结出道岔上关键点求取公式。用数学化的公式代替CAD图中的手动采点,利用程序输出道岔的关键点坐标,再调用OpengFlight API编程,实现了城轨模拟驾驶系统中道岔模型的自动生成,其优点是生成的道岔模型精确,工作量少,为今后利用程序输出道岔上关键点坐标提供了一种算法。

The paper summarized the coordinates formula of the key points on the turnout which was used widely,then adopted mathematical formulas instead of manual sampling sites in the CAD drawing and called OpengFlight API programming to generate turnout model automatically.The advantage was that the generated turnout model was precise.The work load was less than before.The paper provided an algorithm for output key point coordinates on the turnout by programming in the future.
