Comparative analysis and interrelation between haematite suspension based sliders of various configurations influenced with squeeze effects and film ratio under slip conditions

Abstract

The rationale of the current article is to investigate hematite suspension based slider bearings of various configurations namely, inclined, secant, exponential, convex and parallel pad stators under the effect of polarization force. The comparative investigation of the load capacity with reference to the position of centre of pressure under varying squeeze and slip conditions has been carried out. The squeeze velocity seems when the upper pad moves normally towards the lower one. The mathematical articulations for non‐dimensional pressure, load capacity and position of the centre of pressure for various configurations of bearing have been acquired. The optimum values of film ratio concerning maximum load capacity for various designed sliders are analyzed at distinct values of squeeze velocity. The interrelation between parallel, inclined and convex pad stator slider bearings is also explored. Finally, a suggestive approach is made to use a particular design of slider under given dynamic conditions.

Analysis of Magnetic fluid based porous rough short bearing with viscosity variation and elastic deformation

“…Over the years, researchers have continuously explored innovative bearing designs and materials to enhance the performance and reduce friction. One promising avenue of investigation is the utilization of magnetic fluids, which offer unique properties due to their ability to respond to external magnetic fields ( Tipei (1982), Rosensweig (1985), Berkovsky et al (1993), Bhat (2003), Ram et al (2017), Patel et al (2017), Ram et al (2022)). Porous materials have been widely employed in various engineering fields due to their ability to enhance fluid flow, reduce friction and mitigate the detrimental effects of contaminants.…”

Squeeze film derivation of the porous curved annular plates with variable magnetic field, Rosensweig’s viscosity and slip velocity in the Shliomis model

“…The Shliomis model was used by Patel and Deheri (2012) to investigate the impact of transverse surface roughness in a long porous rough journal bearing. Ram et al (2022) studied various bearing configurations influenced by squeeze effects and film ratio and suggested their appropriateness for different squeeze films. Zheng and Tannant (2017) examined the Kozeny-Carman's equation with discrete modelling and finite flow.…”
