为了探究钢轨短波波磨与轨道横向振动位移的相互作用机制，通过现场实测得到钢轨波磨特征以及波磨不同发展阶段的轨道横向振动特征。在此基础上，构建车辆-轨道空间耦合模型，利用USFD磨耗函数计算分析了曲线半径、车速、扣件设计刚度及阻尼对钢轨短波波磨发展的影响。结果表明：钢轨波磨与轨道横向振动位移呈明显的正相关关系；在相同运营条件下，轨道横向振动位移的加剧会提高钢轨波磨发展速度。提高曲线半径和降低运营车速，均会使曲线内轨的横向位移与波磨发展速度逐渐降低。增大扣件阻尼可以有效降低钢轨波磨的发展速度，减缓钢轨横向位移加剧的趋势，扣件垂向阻尼系数取80 kN·s/m时曲线内轨在波磨共振频率800 Hz（波长40 mm）处的磨耗峰基本消失。
Abstract：In order to explore the interaction mechanism between rail short wave corrugation and lateral vibration displacement of the track, the characteristics of rail corrugation and the lateral vibration characteristics of the track at different stages of corrugation development were obtained through on-site measurements. Based on this, a vehicle-track spatial coupling model was constructed, and the influence of curve radius, vehicle speed, fastener design stiffness, and damping on the development of rail short wave corrugation was calculated and analyzed using the USFD(University of Sheffield) wear function. The results show that there is a significant positive correlation between rail corrugation and lateral vibration displacement of the track. Under the same operating conditions, the intensification of lateral vibration displacement of the track will increase the development speed of rail corrugation. Increasing the curve radius and reducing the operating speed will gradually reduce the lateral displacement and corrugation development speed of the rail inside the curve. Increasing the damping of fasteners can effectively reduce the development speed of rail corrugation and slow down the trend of increased lateral displacement of rails. When the vertical damping coefficient of fasteners is set to 80 kN·s/m, the wear peak of the rail within the curve at the corrugation resonance frequency of 800 Hz(wavelength of 40 mm) basically disappears.
