Summary: Fretting wear behavior of steel wire ropes used in coal mine technology is numerically investigated and compared with experimental data in this study. The effect of contact parameters on the fretting wear process is analyzed using a validated three-dimensional Finite Element (FE) model. The results show that higher fretting amplitude and contact load significantly affect wear profile, wear depth, and wear scar. The wear characteristics are also influenced by the contact angle.

Summary: In this study, a finite element simulation method is proposed to consider the fretting wear effect in slip zones of railway axle press-fitted specimens. The real-time calculation of specimen wear depth and the update of contact surface profile in the finite element model are realized, based on the modified Archard wear model. The results show that the fretting wear depth increases with the number of cycles of rotational bending load on the press-fitted axle specimen, with the most severe wear occurring at the edge of the contact surface and 0.1 mm from the edge. The existence of fretting wear leads to the redistribution of contact fretting parameters.

Summary: In this study, fretting wear experiments were conducted on AgNi10 to establish the relationship between electrical contact resistance (ECR) endurance and wear volume. A numerical approach based on a three-dimensional fretting wear model was proposed to predict the ECR endurance under fretting wear conditions. The validation of the numerical approach was conducted by comparing the numerical results with experimental data, showing that it can accurately predict the ECR endurance under various fretting wear conditions.

Summary: Metal rubber (MR) is a damping material with a space-disordered network interpenetrating structure. The wear and fracture caused by mutual extrusion and friction are the main reasons for its fatigue failure. However, the research on the wear of metal wire with curvature inside metal rubber is rarely reported, and the influence of curvature on the wear of spiral metal wire is unclear. A fretting wear evolution model of metal wires with curvature was deduced and constructed in this work to explore the wear characteristics of metal wires with curvature.

Summary: This study investigates the effects of displacement amplitude on fretting fatigue damage using a crossed wires set-up. The results confirm the beneficial effect of wear in the gross slip regime, which reduces contact stresses by extending the contact area. To overcome the computational limitations of using a classical FEM strategy, a hybrid analytical-numerical strategy is developed to efficiently simulate contact geometry modifications.

Summary: This study focuses on the contact and fretting wear characteristics of overhead power lines, considering the concealment of wind vibration and technical problems that can lead to accidents caused by wire and fitting wear. Through analysis of important parameters such as stress during frictional contact, wear morphology, and contact surface pressure during frictional wear, significant conclusions are drawn. By creating a contact mechanics model of the overhead line under wind vibration using three-dimensional modeling software, the study examines the changes in contact stress, micro-displacement, and the relationship between stress and vibration frequency. Fretting properties of adjacent conductor contact points are also calculated and analyzed, providing a mechanical foundation for understanding the wear mechanism of overhead lines.

Summary: The novelty of this study lies in constructing an Entropy-based wear and fluid-solid-thermal (FST) coupled model for journal bearings, and revealing the transient interaction behavior between wear evolution and FST evolution during repeated starting and stopping. The wear rate is measured experimentally, and the contact temperature, friction coefficient and normal contact force are obtained from the validated FST model. Wear tests and numerical calculations are conducted to validate the predicted wear rate and investigate the time-varying wear and FST evolution of journal bearings.

Summary: A polymer coating prepared by liquid spraying technology on the surface of 20CrMo steel demonstrates good tribological and anti-cavitation erosive properties. It can effectively replace CuPb24Sn copper alloy in valve plates for pumps under different lubrication conditions. The coating exhibits adhesive wear and reduces frictional loss, and mainly shows abrasive wear under complex working conditions. Its lipophilicity, high hardness to elastic modulus ratio, and corrosion resistance are the main influencing factors for its performance.

Summary: This study simulated the rolling contact of a driving wheelset over tangent and curved tracks at a speed up to 500 km/h using an explicit finite element approach to derive creep curves. The comparison between quasi-steady curves and transient curves in the presence of rail corrugation helped to identify cases where traditional theories are inapplicable and where transient effects must be considered. Additionally, the study further analyzed the influence of middle/high-frequency vibrations in the presence of rail corrugation.
