论文摘要
车轮和导轨之间的表面粗糙度对滚动噪声水平有很大影响。第三体的存在，例如霜冻或轮轨界面上的油脂有助于变化的粘附系数，从而导致各个级别的噪声产生。因此，可以通过对源自车轮轨相互作用的噪声模式的分析来估算轮子和导轨之间的粘附条件。在这项研究中，提出了一种新的估计粘附条件的方法，该方法将滚动噪声作为输入。
The surface roughness between the wheel and rail has a huge influence on rolling noise level. The presence of the third body such as frost or grease at wheel-rail interface contributes towards change in adhesion coefficient resulting in the generation of noise at various levels. Therefore, it is possible to estimate adhesion conditions between the wheel and rail from the analysis of noise patterns originating from wheel-rail interaction. In this study, a new approach to estimate adhesion condition is proposed which takes rolling noise as input.
