The article deals with the problems of identify of rigidity parameters k and damping parameters c of bearings of hydrodynamic two-stage mixed flow pumps. Bearings with diameters smaller than those used in reality were tested with the use of the principle of geometric and hydrodynamic similarity. The tests were conducted on a specially constructed test station. Parameters of bearings were identified by the method of amplitude-frequency characteristics.
