Faults related to hydrodynamic bearing can imply in high maintenance costs when late-detected and even the total shutdown of system. Thus, techniques early fault diagnosis have relevance reliability rotating machinery. However, a common caused by inadequate oil supply has not yet received appropriate attention. This paper presents new approach model identify starved or excessive bearings. The d...

In this paper, the combined effects of characteristic size and concentration inorganic fullerene-like tungsten disulphide nanoparticles (IF-WS 2 NPs) or molybdenum (IF-MoS on nonlinear dynamic behaviour a gasoline engine crankshaft bearing subject to an arbitrary force torsor (effective applied moment vector) are theoretically numerically investigated using V. K. Stokes micro-continuum theory. ...

In this work we present FELINE, a C++ solver of the Reynolds equation for treating hydrodynamic lubrication problems. To correctly describe cavitation regions, FELINE implements inexact Newton iteration (INE) algorithm within finite element method (FEM) framework. The was tested and validated against known cases in literature industrially relevant dimpled textures. Furthermore, provide benchmar...
