“…They found that the herringbone-grooved bearings exhibit a superior load-carrying capacity compared to the rectangular-grooved bearings. Subsequently, Shinde et al [8] conducted a static characteristic analysis of journal bearing systems with rectangular, circular, and triangular micro-textured grooves and ribs using COMSOL software, version 6.2. It was found that the case with rectangular texture grooves had the lowest oil film pressure and power loss.…”

Aiming to improve the comprehensive performance of the journal bearing system, this paper presents a multi-objective adaptive scale texture optimization design approach. A mixed lubrication model for the textured journal bearing system is established by considering the effects of cavitation and roughness. The geometrical parameters of the textures were co-optimized using a multi-objective grey wolf optimizer to obtain the optimal texture schemes that are suitable for different operating conditions. Through this approach, the influences of different texture schemes under transient operating conditions can be investigated. According to the results, it was found that different texture schemes result in different friction reduction effects. Proper surface texture is beneficial in increasing the minimum oil film thickness and reducing the possibility of asperity contact. The adaptive scale texture exhibits strong adaptability and achieves significant hydrodynamic effects. Therefore, the developed approach provides valuable insights for the optimization design of journal bearing systems.

“…Tong et al 16 used laser deposition to process micro-texture on the surface of cemented carbide, and carried out friction and wear tests on cemented carbide to analyze its tribological properties. Shinde et al 17 studied the effect of triangular, circular and rectangular micro-textured grooves on the surface of the journal, compared with other shapes of micro-texture, the rectangular micro-texture groove had the smallest pressure change and friction power loss. He et al 18 studied the tribological properties of cemented carbide surface under the influence of laser processing parameters and texture parameters.…”

In order to improve the lubrication performance of the friction pair, the effect of composite micro-texture on the lubrication performance of the tilting pad thrust bearing is studied. Based on the structural model of tilting pad thrust bearing considering composite micro-texture, the lubrication characteristics of thrust bearing with composite micro-texture parameters and tilting pad parameters are analyzed. At the same time, the theoretical model of tilting pad composite micro-texture bearing considering roughness and turbulence effect is established, and the performance of thrust bearing considering roughness and turbulence effect is studied. The results show that the performance of composite micro-textured bearings is better than that of single micro-textured bearings, the performance of tilting pad bearings is better than that of parallel pad bearings, and the performance of circular composite fish-shaped micro-textured tilting pad bearings is the best. The optimal bearing fulcrum position is near the inner diameter, and the optimal fulcrum circumferential inclination angle is about 27.5°. Considering the roughness and turbulence effect, the maximum pressure and bearing capacity of the bearing improves, and the friction coefficient significantly reduces.

The present article aimed for investigating the fluid-film pressures for chevron-textured porous journal bearing. The Reynolds equation for porous bearing has been adopted as governing equation, we took the Reynolds boundary conditions into account. The numerical computation has been performed with the help of finite difference methods. The numerical model is well validated with the previous work of researchers. The calculated results revealed that the incorporation of chevron-textures in the convergent zone significantly increase the film pressures as compared to smooth bearing case which ultimately lead to improve the tribological performance. Moreover, permeability play a detrimental role in enhancement of film pressure but incorporation of texture definitely compensate to these effects up to some extent.
