- Leontiev M.K., Snitko A.A., Kornilkov N.A., Davidov A.V., Degtiarev S.A., Rotordynamics of compressor with electromotor supported by AMB
The article presents the results of modeling and analysis of dynamic characteristics of the radial-flow compressor of the “Turbopneumatic” Co Ltd. with the electromotor produced by the SKF company and supported by magnetic bearings. This modeling was done with the help of the Dynamics R4 program system. The tasks of the compressor rotor system optimization are solved by control of tightening torques, interferences and clearances. The results of the compressor analysis as nonlinear dynamic system are given at unsteady statement. The compressor rotor fall on the safety rolling bearings is considered when current is switched off.
