Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 3, November 2023., 2023 Abstract In the realm of lubrication theory, the hydrodynamics of the fluid lubricant are commonly elucidated through the Reynolds equation. Its establishment stems from using the Eulerian description method, restricting the fluid domain to a fixed spatial configuration.

Transient torque reversals in indirect drive wind turbines
Wind Energy, Volume 26, Issue 7, Page 691-716, July 2023., 2023 Abstract The adverse effect of transient torque reversals (TTRs) on wind turbine gearboxes can be severe due to their magnitude and rapid occurrence compared with other equipment. The primary damage is caused to the bearings as the bearing loaded zone rapidly changes its direction.

Tribological Performances of Diamond‐Like Carbon Coatings for Hydraulic Applications
Chemical Engineering &Technology, Volume 46, Issue 1, Page 118-127, January 2023., 2023 Diamond‐like carbon materials in different combinations were coated onto a nitride steel substrate using two different deposition methods. A tribological investigation was performed to find out their suitability for the tribological contacts in hydraulic axial piston pumps. The application of such materials as unleaded alternatives to materials used in

Elastohydrodynamic Simulation of Pneumatic Sealing Friction Considering 3D Surface Topography
Chemical Engineering &Technology, Volume 46, Issue 1, Page 167-174, January 2023., 2023 The influence of the surface topography of the sealing counterface in a pneumatic spool valve on the sealing friction force during operation is investigated. For that, the 3D surface topography of the running surface has been measured optically. Using an elastohydrodynamic lubrication simulation, it could be demonstrated that the surface topography ...

A Tribo‐Dynamic Model of a Helical Gear Pair Based on the Finite Line Contact Theory
Mathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023 In this article, a finite line contact tribo‐dynamics model of helical gears is established by coupling the tooth surface friction, friction moment, and vibration velocity. To obtain convergent results, a cycle iteration strategy is adopted to solve the two submodels, the dynamic model and the thermal elastohydrodynamic lubrication model.

Forecasting the Friction Coefficient of Rubbing Zirconia Ceramics by Titanium Alloy
International Journal of Intelligent Systems, Volume 2023, Issue 1, 2023., 2023 The thermal issues generated from friction are the key obstacle in the high‐performance machining of titanium alloys. The friction between the workpiece being cut and the cutting tool is the dominant parameter that affects the heat generation during the machining processes, i.e., the temperature inside the cutting zone and the consumed cutting energy ...
