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。
By establishing the interaction model between wheel and rail, the influence of the random wheel and rail surface irregularities, especially the short wavelength corrugation wear and different train speed, on the wheel and rail lateral vibration and vibration noise is analyzed. The established model and procedure predict the wheel and rail noise basically coincide with the measured results of the relevant literature.
