“…Besides, during rolling-sliding, debris was drawn into the contact interface and tended to adhered to the faster disc (driving disc), forming a third body layer, which would affect the action state of the contact pressure and the distribution of creepage in the interface, thereby influencing the wear state [34]. For example, Zhou et al [35] found that the wheel and rail wear rates at low temperature were significantly lower than those at room temperature because the faster disc was covered by a third body layer at low temperatures. In this work, although the third body layer was not formed, the surface damage and crack length of the faster rail discs (Fig.…”

“…At present, most researchers focus on material type, limited to a single contact form or mainly consider the impact of ambient temperature (Yezhe et al, 2019;Wang et al, 2017;Luo et al, 2020; The current issue and full text archive of this journal is available on Emerald Insight at: https://www.emerald.com/insight/0036-8792.htm Zhou et al, 2022;Ma et al, 2017). However, there are few studies on the friction and wear properties of materials under high ambient humidity conditions.…”

Purpose The purpose of this paper is to examine the practicability of the self-designed ambient humidity controllable pin-disc/rolling multifunctional friction and wear test device and to evaluate the friction and wear characteristics of materials under diverse ambient humidity conditions in different contact forms. Design/methodology/approach The practicability of the self-designed multifunctional friction tester was examined by the friction and wear tests of materials under different ambient humidity conditions [65%RH, 98%RH (relative humidity)] in diverse contact forms (pin/disc and rolling). Meanwhile, the friction and wear properties of pin/disc samples also rolling samples were assessed from three aspects: average friction coefficient, wear mass and wear morphology. Findings The results prove that the self-designed multifunctional friction tester has practicability. Therefore, it can be used to simulate the friction and wear tests of materials under diverse ambient humidity conditions in different contact forms. Besides, it is evident that the wear damage of pin/disc and rolling samples are greatly improved under high ambient humidity conditions. And when other conditions are identical, the higher the ambient humidity, the smaller the average friction coefficient, wear mass and wear damage degree of pin/disc also rolling samples. Originality/value This paper offers a self-designed multifunctional friction and wear test device. And the tester not only can realize the control of test ambient humidity, but also achieve the wear test of pin/disc or rolling contact forms. The design and production of the tester can offer convenience for the research of tribology, and provide fundamental guidance for the study of materials under high humidity condition in diverse contact forms.

Zhou et al (2020) investigated the wear and damage behavior of three heavy-haul rail steels at laboratory and low temperatures using a rolling sliding wear tester. Based on the material wear theory proposed by Archard, Wang et al (2020a, 2020b) established a numerical prediction model for the development of turnout wear in high-speed railways based on vehicle-turnout coupled dynamics simulation and wheel–rail rolling contact analysis.…”

Purpose With the increased speed and mileage of high-speed lines, the problem of rail wear is increasing. In actual operation, a large number of abnormal wear phenomena occur on both vehicles and rails during fixed line operation; therefore, the purpose of the study is to explored the rail wear for a variety of vehicles running in mixed operation. Design/methodology/approach This paper used the universal mechanism multibody dynamics software to establish the CRH2 high speed train (HST) and the CRH3 HST vehicle dynamic models, respectively. The mixed running of HSTs on the effect of rail wear evolution law was analyzed. The rail wear of the two vehicles with different curve radii, different wheel diameters and different under-rail stiffness was compared and analyzed. Findings The result showed that the rail wear of CRH3 HST is greater than that of CRH2 HST. The rail wear in the tangent track under mixed operation conditions is 25.4% less than when CRH3 HST operated independently. When there is a 1-mm wheel diameter difference, the maximum rail wear of CRH2 HST and CRH3 HST increases by 263% and 44%, respectively. The amount of rail wear is proportional to the under-rail stiffness, and the position of the maximum wear is almost unchanged. Originality/value Most studies on the evolution law of rail wear are conducted for a single vehicle type and a single line. This study explored the mixed running of HSTs on the effect of rail wear evolution law.
