Abstract
Mathematical model of rotor dynamics and test rig with rotor in gas bearings are developed for developing of experiment calculated model of high-speed rotor in gas bearings. Rotor mathematical model includes shaft model and nonlinear support with gasdynamic foil bearing model considering four body contact: shaft-gas film-foils-bearing race. Test rig with rotor in gas bearing for verification of numerical simulation results and for adjustment of small gas turbine units (GTU) shafting performance are developed. First stage of numerical simulations and experimental research are done for investigation of simulator rotor rotation in gas supports. Rotor orbits in supports are received for numerical model and experimental investigation and their comparative spectrum analysis are carried out.
