A Review on the Impact of Bio‐Additives on Tribological Behavior of Diesel Fuels

Advances in Tribology, Volume 2024, Issue 1, 2024.
Automobile engines require lubrication to lessen the impact of friction due to the high levels of wear and frictional heat generated by the sliding parts. Wear and friction will cause engine parts to endure for less time, be less reliable, and require more maintenance. Diesel fuel can potentially be replaced with biodiesel among other fuels.

Performance Analysis of Thermal and Surface Roughness Effect of Slider Bearings with Unsteady Fluid Film Lubricant Using Finite Element Method

Journal of Applied Mathematics, Volume 2024, Issue 1, 2024.
The streamline upwind Petrov‐Galerkin (SUPG) finite element method was used in this study to investigate the thermal and surface roughness effects on an inclined slider bearing with an unsteady fluid film. One‐dimensional transverse and longitudinal surface roughness models were considered with the supposition that roughness is stochastic and has a ...

Bearing Performance Analysis of the Thermal and Surface Roughness Effects by Finite Element Method on Slider Bearings Through Non‐Newtonian Fluid‐Type Lubricant

International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.
The finite element method was used in this study to explore the impact of surface roughness and thermal characteristics on slider bearings with non‐Newtonian power‐law fluid flow lubricant. One‐dimensional transverse and longitudinal surface roughness models were considered under the stochastic assumption that roughness has a Gaussian random ...

Thermal EHL Characteristics Investigation on Axle Box Bearings of Railway Vehicle Based on Slicing Method

Shock and Vibration, 2019
Lubrication failures of axle box bearings can lead to accidents, such as bearing burnout and hot axle cutting. Presently, the modeling of the vehicle-track system dynamics rarely considers the nonlinear contact load of axle box bearings, and this leads ...
