Niu, Liubin (author), Yang, Fei (author), Deng, Xiangyun (author), Zhang, P. (author), Jing, Guoqing (author), Qiang, Weile (author), Guo, Y. (author)In practice, the assessment and treatment of rail corrugation are quantitatively based on the corrugation depth. Wheel–rail vertical forces (WRVF), as a direct reflection of wheel–rail interaction, can give expression to the corrugation depth and thus serve as a key parameter for assessing the corrugation. In this paper, we propose an...journal article 2023
