Transient Thermal Micro-elastohydrodynamic Lubrication Model of Filtering Reducer

工程科学与技术, 2013
:The lubrication condition between the meshing teeth of filtering reducer is complex due to multiteeth contact.In order to solve this problem,an elastohydrodynamic lubrication (EHL) model of filtering reducer was established.The un-uniformed load ...

Analysis of Chaotic Features in Dry Gas Seal Friction State Using Acoustic Emission

Lubricants
In this study, a chaos theory-based characterization method is proposed to address the nonlinear behavior of acoustic emission (AE) signals during the startup and shutdown phases of dry gas seals. AE signals were collected through a controlled experiment

The Influence of Non-Gaussian Roughness and Spectral Properties on Mixed Lubrication for Heavily Loaded Counterformal Contacts

Lubricants
The impact of non-Gaussian height distribution and spectral properties on the lubrication performance of counterformal (point) contacts is quantitatively studied (film parameter, Λ, and asperity load ratio, La) by developing a mixed lubrication model ...

An Experimentally Validated Cavitation Model for Hydrodynamic Bearings Using Non-Condensable Gas

Lubricants
Despite great research effort in recent decades, cavitation in hydrodynamic journal bearings is still a not completely understood phenomenon. In particular, it is unclear which proportions of different cavitation types are present in a bearing.
