摘　　要：为研究抗蛇行减振器阻尼孔径变化对列车运行稳定性、平稳性、曲线通过能力的影响,通过阻尼孔的压力-流量方程得到减振器输出阻尼力与其阻尼孔径关系,在Matlab中建立减振器阻尼特性模型,分析抗蛇行减振器在不同阻尼孔径时阻尼特性的变化,将不同的阻尼特性曲线输入到Adams/Rail中,分别建立抗蛇行减振器阻尼孔径不同的高速车辆拖车整车模型,对不同抗蛇行减振器阻尼孔径的列车进行多工况分析。结果表明:在稳定性方面,抗蛇行减振器阻尼孔径的减小可以提高列车非线性临界速度。在平稳性方面,阻尼孔径的变化主要影响列车的轮轴横向力和横向平稳性指标,对垂向平稳性影响较小。在通过曲线时,脱轨系数和轮重减载率随着阻尼孔径的减小而降低,但变化不大。In order to research the effect of the damping hole＇s change of anti-hunting damper on the vehicle＇s stability, runningperformance and the curve passage capability, the relation between the damper force and the damping hole＇s diameter was calculatedby the pressure-flow equation. The change of the anti-hunting damper＇s diameter was analyzed by software Matlab and imported intosoftware Adams/Rail. The multi-body dynamic models of high-speed vehicle with different damping characteristic were set up in Adams/Rail. And the models were calculated under various working conditions. Results were that： In terms of the stability of the vehicle, thenonlinear critical velocity of the high-speed train could increase by the influence of the damping hole＇s decline. And in terms of therunning performance of the vehicle, the wheel/rail lateral force and the lateral ride comfort index were influenced by the change of thedamping hole＇s diameter significantly. However it had little affect on the derailment and the unloading of the vehicle on curve track.
