Performance analysis of thrust pad bearing using micro-rectangular pocket and bionic texture

J. C. Atwal et al.

Summary: This paper presents the performance behaviors of a hydrodynamic thrust bearing with new pad surface designs, including microrectangular pocket and Labeo rohita fish scale texture. The effects of texture parameters on improving bearing performance have been explored, with the microrectangular pocket and fish scale texture design showing significant increases in minimum film thickness and reductions in friction coefficient compared to other designs.

The effect of V-shape protruded and dimple textured on the load-carrying capacity and coefficient of friction of hydrodynamic journal bearing: A comparative numerical study

Sanjay Sharma et al.

Summary: This comparative numerical study analyzed the performance of V-shape protruded, dimple textured, and untextured bearings, finding that the load-carrying capacity and coefficient of friction are maximized for the protruded textured bearing under certain conditions.

Dynamic characteristics of compound textured journal bearing

Fanming Meng et al.

Summary: This study investigates the compound texture effect on the dynamic characteristics of the journal bearing film, finding that the reasonably arranged compound texture can significantly increase the direct stiffness coefficients and damping coefficients of the bearing-rotor system, resulting in higher critical speed.

Fast laser surface texturing of spherical samples to improve the frictional performance of elasto-hydrodynamic lubricated contacts

G. Boidi et al.

Summary: This study demonstrated the potential of fast laser texturing techniques in improving the tribological performance of bearings and mechanical components. Dimples were found to reduce friction effectively compared to smooth surfaces, while grooves had less beneficial effects. Additionally, dimples promoted the formation of full film lubrication conditions at lower speeds.
