摘要:
在某些特殊地段，工程上希望设置内轨高度大于外轨高度的反超高，而目前尚无对反超高曲线设置及其车辆通过安全性等问题的相关标准。通过建立有轨电车动力学模型和槽型轨轨顶外形模型，研究了列车以不同的速度通过槽型轨的不同反超高量曲线时，有轨电车系统的运行安全性和乘客的乘坐舒适性。研究结果表明，反超高量在0~50 mm范围内时，列车运行速度低于46.8 km/h时满足安全性和平稳性要求；反超高量在0~20 mm范围内时，列车以低于54.0 km/h的速度运行是安全、平稳的。槽型轨轨道可以设置反超高曲线。
Abstracts:
In some special areas, it is expected to set the negative superelevation of inner rail higher than outer rail from engineering perspective. At present, related standards of setting negative superelevation and vehicle passing safety are not established. By establishing the tram dynamics model and the groove rail top profile model, the tram system operation safety and passenger riding comfort under conditions of train passing through groove rail with different negative superelevation curves at different speeds are studied. Research results show that, when the negative superelevation is within the range of 0 mm to 50 mm, it is safe and stable for the tram to operate at a speed lower than 46.8 km/h; when the negative superelevation is within the range of 0 mm to 20 mm, it is safe and stable for the tram to operate at a speed lower than 54 km/h. Groove rail can be set with negative superelevation curve.
