摘要

轮径差的出现会影响高速车辆通过道岔时的动态性能，尤其是侧向过岔的情况。为进一步揭示其影响规律，本文以高速车辆和18号高速道岔为例，建立车辆—道岔耦合动力学模型，分析不同轮径差下高速车辆以80km/h侧向过岔时的动力学特性。结果表明，大轮径位于尖轨侧时，等值同相轮径差会减小轮轨横向力和车体横向加速度；大轮径位于基本轨侧时，等值反相轮径差会增大高速车辆侧向过岔时的脱轨系数和轮重减载率。由于实际运营中高速车辆轮径差类型不确定，应尽量避免轮径差超过1mm，以确保高速车辆侧向过岔时的安全性与平稳性不受影响；尖轨侧车轮轮径大于基本轨侧时车轮磨耗加剧，故应避免此类情况发生，以延长车轮和钢轨的寿命。

Abstract

Wheel diameter difference will have an impact on the dynamic characteristics of vehicle passing through turnout, especially in the diverging route being. To reveal the influence mechanism, this paper takes a high-speed vehicle and a No.18 turnout into consideration to build a vehicle-turnout coupling model. The dynamics performance of high-speed vehicle passing through the turnout in the diverging route at a speed of 80 km/h under different scenarios of wheel diameter difference are carried out. The results showed that when the equivalent same-phase (wheels on the same side are all with smaller wheel diameters than the others) wheel diameter difference and the large wheel diameter is located on the side of the switch rail, the wheel-rail lateral force and the lateral acceleration of the car body will reduce. When the wheel diameter of the wheel on the stock rail side is larger than that on the switch rail side, the derailment coefficient and wheel load reduction rate will increase by equivalent counter-phase (The bigger wheel of the front wheel pair is in the opposite position to the bigger wheel of the rear wheel pair) wheel diameter difference when high-speed vehicles passing through turnout in the diverging route. Because of the uncertainty of wheel diameter difference during the real train operation, it should be avoided more than 1mm as far as possible to ensure the safety and stability of high-speed vehicle passing through the turnout in the diverging route. In addition, wheel wear is exacerbated when the wheel diameter of wheel on the switch rail side is larger than that on the stock rail side, so such situation should be avoided. As a result, life span of both wheel and rail could be prolonged.
