Rotordynamik von Turboladern, rotordynamics of turbochargers

Rotordynamics

The rotordynamics of turbochargers are significantly influenced by the non-linear behaviour of the floating bushing bearings. To determine the harmonic and subharmonic oscillations as well as the stability limits, FIRST allows to consider the entire system - consisting of rotor, compressor and turbine wheel - as elastic bodies and couple them with the non-linear inner and outer lubricant film of the floating bushing.
