The effect of top rail lubricant composition on adhesion has been investigated using a laboratory ball-on-disc tribometer. Rheological properties were analysed viscosimeter and high pressure torsion device. As base medium, biodegradable ester oil with bentonite thickener was selected. Added particles for friction modification aluminium oxide, zinc copper sulfide solid lubricants molybdenum disulfide graphite. these components in the medium evaluated. It found that most dominant component...
This study aimed to clarify the protective effect of Glycyrrhizic acid (GL) against Diosbulbin B (DB) - induced liver injury in mice and investigate its mechanisms action. A DB was established through oral administration for 15 days. At same time, GL administered treatment. After experiment, pharmacodynamics ameliorating DB-induced were explored using biochemical indexes, non-targeted metabolomics, targeted Western blotting analysis protein expression, 16S rDNA sequencing, Spearman...
Abstract In railway network, friction is an important factor to consider in terms of the service behaviors wheel-rail system. The objective this study was investigate effect a solid modifier (FM) environment. This achieved by studying friction, wear, and rolling contact fatigue (RCF) damage on materials at different slip ratios. results showed that when FM applied, coefficient decreased. After separated from interface, gradually increased its original level. With application FM, wear rates...
This study aims to deeply understand the effect of contact stress and slip ratio on wear performances bainitic rail steels. The results showed that loss increased as increased. Based surface damage morphology microstructural analyses, it revealed rolling fatigue mechanism played a significant role under low ratio, but dominant transferred abrasive at high ratio. Meanwhile, steel specifically presented worse resistance mode. Compared with influence increase in led severer plastic flows...
Many factors could affect the grinding force during rail processes. Therefore, modeling is necessary for predicting forces under different parameter conditions. In this study, 3D models of wheels were constructed based on surface topographies real wheels. By means simulation processes using DEFORM-3D, influences parameters explored. Furthermore, in order to verify results, experiments conducted a friction testing apparatus. Both and experimental results showed that increased with pressure...
