RISA Mixed Soft Elastohydrodynamic Lubrication Model With Interasperity Cavitation and Surface Shear Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A deterministic mixed lubrication model, governing the interface between a moving smooth rigid surface and a stationary rough elastic surface, has been developed. Both the normal and shear ...
A Mixed-TEHD Model for Journal-Bearing Conformal Contacts—Part I: Model Formulation and Approximation of Heat Transfer Considering Asperity Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mixed-TEHD (thermal elastohydrodynamic) model was developed for journal bearings working at large eccentricity ratios in order to facilitate a better understanding of mixed-lubrication phenomena ...
Numerical Study of a Rotary Lip Seal With a Quasi-Random Sealing Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In all previous numerical simulations of the rotary lip seal, the sealing surface was modeled by regular periodic structures. In the present study, a more realistic quasirandom surface is used. ...
A Mixed-Lubrication Study of Journal Bearing Conformal Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical analyses of finite journal bearings operating with large eccentricity ratios were conducted to better understand the mixed lubrication phenomena in conformal contacts. The average Reynolds ...
A Mixed-TEHD Model for Journal-Bearing Conformal Contact—Part II: Contact, Film Thickness, and Performance Analyses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Investigation of the mixed lubrication of journal-bearing conformal contacts is very important for failure prevention and design improvement. This paper studies the asperity contact in heavily ...
Simulations and Measurements of Sliding Friction Between Rough Surfaces in Point Contacts: From EHL to Boundary Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a numerical approach to simulate sliding friction between engineering surfaces with 3D roughness in point contacts. The numerical approach is developed on the basis of the ...
