Numerical Modeling of Wear in a Thrust Roller Bearing under Mixed Elastohydrodynamic Lubrication

Abstract: Increasing efforts to reduce frictional losses and the associated use of low-viscosity lubricants lead to machine elements being operated under mixed lubrication. Consequently, wear effects are also gaining relevance. Appropriate numerical modeling and predicting wear in a reliable manner offers new possibilities for identifying harmful operating conditions or for designing running-in procedures. However, most previous investigations focused on simplified model contacts and the wear behavior of application-ori… Show more

“…The involved wear mechanisms in each stage, the interaction among wear mechanisms in each stage, the surface topology changes and the influencing factors within each stage were all illustrated (El-Thalji and Jantunen, 2014). To explore the wear behavior of application-oriented contacts, Winkler et al provide a numerical procedure for studying the wear evolution of cylindrical roller thrust bearing (CRTB, 81212) in the mixed elastohydrodynamically lubricated (EHL) roller/raceway contact through a finite element method (FEM)-based 3D EHL model, considering realistic geometry and locally varying velocities (Winkler et al , 2020). Rosenkranz et al critically summarized the state of the art of surface texturing applied to machine elements and provided some general design guidelines for surface texturing in machine elements (e.g.…”

“…Mixed lubrication was taken into account by a statistical approach since a deterministic consideration of surface roughness would require very fine meshing and high computational efforts due to the large contact sizes in soft EHL contacts. Therefore, the Greenwood–Williamson model [ 90 ] was utilized and the solid contact pressures p a versus the local fluid film parameter: due to the micro-scale deformations of asperities were derived in a preceding simulation in MathWorks MATLAB following [ 91 ] and incorporated into the macro-EHL simulation as interpolated functions. The corresponding curves for the pairings studied in this contribution are summarized in Figure 2 b.…”

“…For elastic deformation, the Young's modulus and the Poisson's ratio must also be normalized accordingly. Since the calculation of the finite line contact in this form leads to a very long calculation area in y-direction with a correspondingly high simulation effort because of the used mesh, the y-axis was compressed by a scaling factor S, as described by WINKLER [45]. The scaling was thus directly included in the calculation of structural mechanics and hydrodynamics.…”
