Originální abstrakt

This paper deals with the measurement and computational modelling of the static equilibrium position of the hydrodynamic water-lubricated tilting-pad journal bearing. The measurement is carried out on a developed test rig with two bearing housings. A computational model is presented based on the generalized Reynolds equation coupled with the 2D energy equation in the bearing midplane. This model includes the lubricant mixing, deformation and tilting of the pads. The steady-state solution is reached using the finite volume method. To find the static equilibrium position of the bearing, the Anderson method with bounds is implemented. Results of the equilibrium position in dependence on the journal speed are given for a particular water-lubricated journal bearing. These results are validated with the measured data.
