Rolling contact fatigue and wear of two different rail steels under rolling–sliding contact

Experimental Investigation on the Wear and Damage Characteristics of Machined Wheel/Rail Materials under Dry Rolling-Sliding Condition

“…(2). The contact mode between the wheel/rail discs is line contact, as per [18], the maximum Hertzian contact stress is expressed in Eq. 3.…”

“…The adhesion coefficient µ can be calculated with the readings of the load sensor and the torque transducer, as formulated by Equation (2). The contact mode between the wheel/rail discs is line contact, as per [18], the maximum Hertzian contact stress is expressed in Equation 3.…”

“…Up to date, researches on the tribological performance of wheel/rail materials mainly focus on the laser-related treatment of wheel/rail materials [9][10][11][12][13][14][15], the wheel/rail hardness matching [16,17], the selection and matching of wheel/rail materials [18] and various wheel/rail creep ratios [19]. As a potential and promising technique to extend the railway component service life, laser cladding technology performed on rail steels can improve and enhance their microstructural and mechanical properties [9,10,13], increase the hardness and enhance the wear resistant performances [9,14,15] and affect the residual stress distribution of laser-cladded rails [20].…”

Wear and damage transitions of wheel and rail materials under various contact conditions

“…This was used initially by Bolton and Clayton [26] and then in a number of subsequent studies [5,7,13,[27][28][29][30].…”

Experimental evaluation of rolling contact fatigue in railroad wheels

“…Interactions between RCF and wear of rails were recently analyzed by Seo et al [12]. The test specimens did not have the same dimensions of the real components, but were taken from the rim of a wheel and the head of the rail.…”
