THE SOLUTION OF LUBRICATION AND COUPLED ANALYSES USING THE FINITE ELEMENT METHOD

Finite element analysis offers the ability to handle, with ease, complex geometrical shapes and abrupt changes in field properties. The established finite element software available within the PAFEC suite of subroutines has been modified and added to so that the laminar hydrodynamic equation for any rigid, isothermal, steadily loaded bearing can be solved. Using the other facilities available, the analysis is extended to handle elastohydrodynamic solutions. In order to analyse flexible bearings, structural analysis is also required. The pressures developed within the oil film form the link between the two types of analysis. This paper presents a summary of the lubrication analysis available using PAFEC. The basic analysis involves specifying the oil film geometry. Iteration is required for analyses involving specified loads. An example of piston ring locus prediction is given to demonstrate this. Results are also detailed in the field of elastohydrodynamic lubrication.
