摘　　要：合理设置曲线超高对提高列车运行舒适性、减少轮轨磨耗、节省铁路工务作业成本具有重要意义。为进一步提高我国当前的路网运输效率,对高速铁路兼顾普速客车上线的曲线超高设置问题展开研究。基于车辆—轨道耦合动力学理论计算高速及普速列车的动力响应,采用模糊多准则优选算法对高速列车和普速列车的运行舒适性Sperling指标进行优化。以通过相应曲线半径的过超高和欠超高允许值作为约束条件,建立基于模糊层次分析法的高速(250 km/h)兼顾普速(160 km/h)线路曲线超高的多准则优选模型。研究结果表明:本文采用的模型能够同时满足高速与普速铁路的舒适性需求,可为高速兼顾普速线路的超高设计提供参考依据。Reasonable setting the superelevation of railway curve is of great significance to improve train operation comfort, reduce wheel-rail wear as well as save the railway maintenance cost. To further improve the transportation efficiency of our country ’ s current railway network, this paper studied the problem of setting the curve superelevation of high-speed railway and the operation of ordinary-speed trains. First, dynamic responses of high-speed and ordinary-speed trains were calculated based on vehicle track coupling dynamics theory, and then fuzzy multi-objective optimization was performed to maximize the running comfort(Sperling Index) of highspeed train and ordinary-speed train. By taking the allowable values of the high and low super-elevation as the constraints when trains pass through the corresponding railway curve, a multi-objective optimization model was established for high speed(250 km/h) and ordinary-speed(160 km/h) line ’ s curve super-elevation. The findings can provide technical reference for the design of the high-speed and ordinary-speed line ’ s super-elevation.
