Special Issue Information
Dear Colleagues,
After the successful publication of the first edition of the Special Issue "Tribological Characteristics of Bearing System", we are excited to announce that the second edition is now open for submissions.
Bearings are widely used in automobile transmission, rail transit, and aerospace and equipment manufacturing. They are the key mechanical components for bearing and transmitting motion. Under severe conditions, such as large load, high speeds, and wide temperature ranges, the study of bearing friction and wear characteristics and the fatigue damage mechanism is significant for promoting the high reliability, durability, and long life of bearings. With advanced intelligent manufacturing technologies, such as bearing material alloy optimization, heat treatment process optimization, deformation prediction, surface modification and intelligent simulation, new technical support and development ideas can be provided for bearing systems.
This Special Issue will present a collection of papers on bearing friction and wear, fatigue durability, and rotor dynamics, representing the latest research progress in this field. I am pleased to invite researchers in related fields to contribute to this Special Issue.

1. Title: Carrying Capacity of Spherical Hydrostatic Bearings including hydraulic oil viscosity and dynamic pressure
Authors:Shengdong Zhang, Guangming Li, Xiuying Yang, Yongchao Cheng, Jichao, Li, Wenlong Song, Dongjiang Yang
Abstract: This paper presents a theoretical model for calculating the carrying capacity of spherical hydrostatic bearings, including the deduction and solution of differential equations for fluid flow in the oil seal and the generation of bearing characteristic parameters. The influence law of hydraulic oil viscosity and dynamic pressure effect on the carrying characteristics of liquid hydrostatic spherical bearings is revealed. Hydraulic oil viscosity mainly affects the bearing oil spillage flow, especially when the high pressure oil chamber pressure is large and the hydraulic oil viscosity is small, the oil spillage flow changes greatly. Under general working conditions, the dynamic pressure effect caused by the radial eccentricity of the bearing has little influence on the bearing load characteristics parameters, when the minimum width of the gap between the sealing edge is very small, and the bearing rotational speed is high, the dynamic pressure effect is more obvious.
Keywords: spherical hydrostatic bearing; carrying capacity; Navier–Stokes equation; hydraulic oil viscosity; dynamic pressure

2. Title: Effect of deformable roughness on the Ferro-fluid based squeeze film between a sphere and a flat plate in the existence of couple stress

Abstract: • This article aims to study the impact of ferrofluid in the presence of couple stress between sphere and flat plate on the basis of Christensen and Tonder’s theory for hydrodynamic lubrication of rough surface. • Neuringer-Roseinweig model (NRM) is implemented for the effect of ferro-fluid. The modified Reynolds equation accounting for the ferrofluid and surface roughness in the presence of couple stress is mathematically derived. • To obtain the bearing characteristic such as pressure distribution and load carrying capacity, the modified Reynolds equation is derived using associate pressure boundary conditions. • It is noticed that there is significant enhancement is found in load carrying capacity due to the combined influence of ferrofluid and couple stress in the case of transverse surface roughness.
Highlights: Deformable surface roughness (DRS) on the flat plate notably affects the characteristics of the squeeze film. The direction of this influence whether it increases or decreases depends on the specific roughness pattern and porosity. Azimuthal (radial) roughness pattern on the flat plate leads to a significant increase or decrease in load carrying capacity compared to a smooth surface.
