Contact fatigue issues are becoming more prominent in current gear anti-fatigue designs.
Surface wear may result in unavoidable occurrence competition among contact fatigue …

Innovative stiffness and damping models for oil films are developed to account for the
impacts in both normal and tangential directions. Given that these models are applied to a …

A new normal stiffness model of the oil film is established by the viscous-elastic fluid
between a spur gear drive being equivalent to a massless spring element, and the …

An enhanced spur gear dynamic model considering the combined stiffness and damping of
both gear tooth and oil film is established. To acquire the combined stiffness and damping …

This work aims to propose a roller bearing model introducing a concept of reduced contact
force model under elastohydrodynamic lubrication (EHL) by a set of equivalent contact …

Elastohydrodynamic lubrication (EHL) plays a crucial role in reducing surface deformation
and friction, leading to improved stability and reliability of gear transmissions. A model is …

Contact fatigue issues become more and more crucial in gear industry as they significantly
affect the reliability and service life of associated mechanical systems such as wind turbine …

In this paper, the time-varying stiffness of the cylindrical roller bearing due to the thermal
behavior, ie warm-up process and different lubricant oil temperatures are experimentally …

Owing to backlash, the drive-and back-side meshing points have an asymmetric relationship
relative to the initial positions of the respective line of meshing. This study investigates the …
