Study on Rotor-Bearing System Vibration of Downhole Turbine Generator under Drill-String Excitation
Downhole turbine generators (DHTG) installed within drill-string are susceptible to internal and external excitation during the drilling process, causing significant dynamic loads on bearings, and thereby reducing the bearing’s service life. In this study, a finite element model of an unbalanced rot...
