摘要/Abstract

摘要： 轨道短波不平顺是引起轨道-车辆系统高频振动的主要根源，造成轮轨之间剧烈的相互作用力。利用ABAQUS计算软件显式模块建立的轮轨接触有限元模型，用于求解车辆高速运行时轨道短波不平顺作用条件下的高频轮轨接触力。该模型采用轮轨的真实形状建模，并且可引入任意形状的轨道短波不平顺及轨道状态参数。以某高铁线路上实测轨道短波不平顺作为输入，接触模型仿真输出的轮轨垂向力与高速综合检测列车在对应区段上实测轮轨垂向力数据之间的相关系数为0.82，验证了所建模型的正确性。利用高频轮轨模型计算不同速度条件下不同参数的余弦型轨道短波不平顺引起的动态轮轨垂向力，对比分析计算结果表明：动态轮轨垂向力不仅与轨道短波不平顺的幅值有关，还车辆与轨道短波不平顺波长敏感程度有关，在车辆运行速度不低于200 km/h的条件下，车辆对轨道短波不平顺的敏感波长分布在100～200 mm。

Abstract: Short track irregularity is main source of high frequency dynamic wheel/rail vibration, causing intense interaction force between wheel and rail. high frequency wheel/rail contact model built by ABAQUS/EXPLICIT software module can solve the contact force between wheel and rail under the conditions of track short wave irregularity in high speed. The parameters of this model come from the real shape and size of the wheel and rail, and can introduce arbitrary shapes of track short wave irregularity and rail state parameters. under the real high-speed railway short wave track irregularity conditions, the correlation coefficient between the measured wheel rail vertical force from high-speed inspection car and the wheel rail vertical force from the model is 0.82, which verify the correctness of the model. By comparing the dynamic wheel rail vertical forces caused by track short wave irregularities of different cosine shapes in multiple speeds. The result shows that the dynamic wheel rail vertical force related with track short wave irregularity amplitude, and the sensitive wavelength of the track irregularity. In the condition of the vehicle speed not less than 200 km/h, the sensitive wavelength in track short wave irregularity between vehicle and rail is 100-200 mm.

Key words: explicit transient analysis, high frequency wheel/rail contact model, track short wave irregularity, wheel/rail contact force
