Test Stand for Study of Oscillations of Turbin Rotors in Bearings with Gas Hydrodynamic Lubrication

Abstract

A test stand was designed for investigations of rotor vibrations caused by a misalignment, by resonant phenomena, and by the loss of stability in the lubricating layer. Antifriction bearings and different slide bearings with an oil or gas lubricant can be used as rotor supports. One support of the test stand is adjustable, and a set of rotors with detachable disks is provided. The stand is suitable for studying rotors up to 1240 mm long and 350 mm in diameter. It can also be used to study vibrations caused by misalignment of the bearings, and to study the external damping, the centering of bushings, and the possibility of modeling the turbing flow passage.
