Fixed frog and wheel rail contact structure design method and rail transit structure
The invention discloses a fixed frog and wheel-rail contact structure design method and a rail transit structure. The method comprises the following steps that S1, the wheel-rail contact bearing width is analyzed according to the wheel-rail contact static geometrical relationship; s2, setting a wheel-rail contact form according to the bearing width of wheel-rail contact; and S3, the frog structure is designed according to the set wheel-rail contact form. According to the design method, the concept of the minimum allowable bearing width is put forward, depth theoretical support is provided for the design of the fixed frog wheel structure again, the structural design of the fixed frog structure is effectively guided, the fixed frog structure better meeting the actual application environment requirement is obtained, the influence of a harmful space on rail transit is reduced, and the service life of the rail transit is prolonged. And the overall stability and safety of the rail transit structure are effectively improved.
本发明公开了一种固定型辙叉与轮轨接触结构设计方法及轨道交通结构，包括以下内容：S1.根据轮轨接触静态几何关系分析轮轨接触的承载宽度；S2.根据轮轨接触的承载宽度设定轮轨接触形式；S3.根据设定的轮轨接触形式设计辙叉结构。本设计方法提出了最小允许承载宽度概念，重新为固定型辙叉轮结构设计给出了深度理论支撑，有效指导固定型辙叉结构的结构设计，得到更符合实际应用环境需求的固定型辙叉结构，降低‘有害空间’对轨道交通造成的影响，有效提高轨道交通结构整体稳定性、安全性。
