Zhao, X. (author), Huang, Shuangchao (author), Yin, Shan (author), Yang, Jizhong (author), Yang, Z. (author), Tao, Gongquan (author), Wen, Zefeng (author)A time-domain finite element model is developed to study the transient rolling contact of a driving wheelset over a curved track with Low Adhesion Zones (LAZs) shorter than 1.0 m. LAZs on one rail, i.e., unilateral LAZs occurring more likely, is treated for a speed up to 500 km/h. Structural vibrations of wheelset are analyzed to explain the...journal article 2023
