摘要为提升道岔侧向通过性能，结合道岔结构特点，提出通过降低侧股内轨导曲线的方式达到在道岔设置超高的目的。以42号道岔为例，设计了加设超高的三次曲线+三次曲线组合线型和加设超高的七次曲线+七次曲线组合线型两种新线型，建立了车辆-道岔动力学耦合模型，经过动力学计算，对比不同工况下的脱轨系数和轮轨横向力，发现在导曲线设置超高和使用高次曲线是有效的，较现有线型能提高车辆侧向过岔的安全性和过岔速度。在设计速度下新线型的脱轨系数极值与现有线型相比降低幅度在14.4%~20%之间，轮轨横向力极值降低幅度在14.5%~26.4%之间。

Abstract：In order to improve the passing through branch lines performance of the turnout, combined with the structural characteristics of the turnout, it is proposed to reduce the guide curve of the inner rail of the side strands to achieve the purpose of setting the superelevation in the turnout. Taking the 1:42 turnout as an example, two new line types: the cubic curve & cubic curve and the 7th curve & 7th curve, were designed to establish vehicle-turnout dynamics. Learn the coupling model and compare the derailment coefficient and wheel-rail lateral force under different working conditions. It is found that setting the superelevation and using the higher-order curve in the guide curve is effective, which can improve the safety and speed of the vehicle compared with the existing type. The extreme value of the derailment coefficient of the new alignments is reduced by 14.4%-20% compared with the existing, and the extreme value of the wheel-rail lateral force is reduced by 14.5%-26.4%.

Key words： railway turnout superelevation multi-body dynamics guide curve
