摘要

车轮出现轮径差会加剧转向架蛇行失稳，电机弹性架悬结构能有效改善其稳定性。为了探明轮径差与电机弹性架悬转向架横向稳定性关系，建立轮轨非线性接触模型和电机弹性架悬转向架横向动力学模型，分析轮径差与电机悬挂参数对转向架横向稳定性影响，研究轮对在不同轮轨接触下Hopf分岔特性。研究结果表明：在同相轮径差下，转向架系统稳定性随电机横移频率增加呈现先增后减趋势，存在最佳频率约为3Hz。当电机振动频率和转向架蛇行频率一致，且幅值越低于后者，电机架悬减振效果越好，但轮径差的产生会降低这一效果；当车辆速度过高且轮径差值超过1.2mm时会导致轮轨发生轮缘接触，短期内提升转向架稳定性，但长期会加剧轮轨磨损。轮径差值越大，轮对平衡中心线越偏离轨道中心线，轮对系统越容易从亚临界Hopf分岔转变为超临界Hopf分岔。同相轮径差工况下轮径差临界值为0.5mm，前轮对轮径差临界值为1.5mm。

Abstract

Wheel diameter differences can intensify the hunting instability of the bogie, and a motor suspension structure with elasticity can effectively enhance its stability. To elucidate the relationship between wheel diameter differences and the lateral stability of a motor-suspended bogie, a nonlinear wheel-rail contact model and a lateral dynamic model of a motor-suspended bogie is established. These models are used to analyze the effect of wheel diameter differences and motor suspension parameters on the lateral stability of the bogie. Additionally, this paper investigates the Hopf bifurcation characteristics of wheelsets under different wheel-rail contact conditions. The research results showed that under the condition of in-phase wheel diameter difference, the stability of the bogie system first increases and then decreases with the increase of the motor's lateral frequency, with an optimal frequency of approximately 3Hz. When the frequency of the motor matches the hunting frequency of the bogie, and its amplitude is lower than that of the latter, the vibration reduction effect of the motor suspension is better. However, the generation of wheel diameter difference will reduce this effect. When the vehicle speed is too high and the wheel diameter difference exceeds 1.2mm, it will lead to flange contact between the wheel and rail. This can enhance the stability of the bogie in the short term, but it will intensify wheel and rail wear in the long term. The larger the wheel diameter difference, the more the balance centerline of the wheelset deviates from the centerline of the track, making the wheelset system more likely to transition from a subcritical Hopf bifurcation to a supercritical Hopf bifurcation. In-phase operating conditions, the critical value for the wheel diameter difference is 0.5mm, and the critical value for the front wheelset diameter difference is 1.5mm.
