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.

轮轨接口状态估计（W-RICE）

轮轨之间的表面粗糙度对滚动噪声水平有很大的影响。轮轨界面处第三种物体（例如霜或油脂）的存在会导致粘附系数发生变化，从而导致产生各种级别的噪音。因此，可以通过分析源自轮轨相互作用的噪声模式来估计轮轨之间的粘附条件。在这项研究中，提出了一种新的估计粘附状态的方法，该方法将滚动噪声作为输入。
