MATLAB结合AutoCAD在无交叉线岔设计中的应用

Application of MATLAB Along with AutoCAD in Design of Non-crossover Turnout

研究目的:随着铁路客运专线道岔侧向及正向通过速度的提高,高速接触网设计对道岔处的定位方式提出了更高的要求。客运专线采用的无交叉线岔设计,不但要保证列车从正线高速通过时不受侧线接触悬挂的影响,而且还要确保从正线驶向侧线或从侧线驶入正线时都能平稳、顺利地过渡。因此不能简单的利用"标准定位"和"非标准定位"的方式对道岔支柱和悬挂进行布置,而应通过一些明确的概念进行精确布置。研究结论:在客运专线车站设计中采用MATLAB结合AutoCAD方法指导无交叉线岔设计,明确接触线、悬挂支持装置与受电弓的几何位置,使得设计形象化、简单化、合理化。所以该方法能够保证受电弓在道岔区段安全、平滑、无障碍的通过,实现300 km/h以上速度的安全行车和接触网受电弓的良好受流。

Research purposes： With the increase of the train speed on the turnout of passenger dedicated line, the catenary design requires more precise positioning on turnout. If the non - crossover turnout design is adopted on passenger dedicated line, it not only guarantees that there is no influence from catenary suspension on side track, but also guarantees train can run from main track to siding or from side track to main track stably and smoothly, so the precise calculations should be done for the turnout post and catenary suspension. Research conclusions： Application of MATLAB along with AutoCAD in design of non - crossover turnout can define the physical positions of catenary, suspension device and pantograph and make the design figurative, simple and reasonable. With this method, the pantograph can pass through the turnout area safely and smoothly with perfect collecting current at the train speed of 300 km/h.
