摘　　要：导轨式胶轮系统超高率是工程设计中的重要参数之一,超高率取值的合理与否,对其工程设计、建设、运营均有重要影响。基于导轨式胶轮系统走行部内嵌于轨道梁的特点,结合不同轨道交通制式超高率设计取值情况,及国内外超高试验成果,为提高导轨式胶轮系统乘客舒适度、旅行速度,充分发挥胶轮系统车辆的优势,研究建议:导轨式胶轮系统最大超高率取值应充分考虑曲线临停状态下未平衡加速度,建议减少最大超高率12%的应用频次,在稍困难条件下可取10%;考虑日本与意大利未被平衡加速度取值方案,建议欠超高取值在既有规范6%的基础上可适当提高,但建议不超过8%。The curve superelevation rate of beam-guiding rubber-tyred system is one of the important parameters in engineering design,and the reasonable value of curve superelevation rate has an important influence on its engineering design,construction and operation.Based on the characteristics of beam-guiding rubber-tyred system embedded in the track beam,combined with the design value of different rail transit system curve superelevation,and domestic and foreign curve superelevation test results,in order to improve the passenger comfort and travel speed of beam-guiding rubber-tyred system,give full play to the advantages of rubber wheel system vehicles,the research suggestions are as follows:The value of the maximum curve superelevation rate of the beam-guiding rubber-tyred system should fully consider the unbalanced acceleration under the curve stoppage state,and it is recommended to reduce the application frequency of the maximum curve superelevation rate of 12%,and 10% under slightly difficult conditions.Considering the unbalanced acceleration value scheme in Japan and Italy,it is suggested that the under superelevation value can be appropriately increased on the basis of the existing standard 6%,but it is recommended not to exceed 8%.
