轨道交通轮轨横向振动噪声分析

Analysies on Wheel Rail Noises and Transverse Vibration

通过建立车轮与轨道相互作用模型,分析了考虑轮轨表面随机不平顺、尤其是短波长的波纹型磨耗以及不同列车速度时,对轮轨横向振动和振动噪声的影响。建立的模型和程序预测的轮轨噪声与有关文献的实测结果基本吻合。

This paper analyzes the effects resulted from vertical and transverse vibrations of the wheel and the wheel/rail noises, by establishing a wheel/rail interaction model and taking into account the random irregularities of the wheel/ral surfaces, holds that the computational results are mainly identical with the developed model and the related documents, thus the analysis is proved to be feasible and effective.
