ROTOR-BEARING DYNAMICS DESIGN TECHNOLOGY. PART 1: STATE-OF-THE-ART

The basic aspects of rotor-bearing dynamics have been collated and are here presented in systematic fashion. The rotor-bearing system and its forces are first discussed. The properties of rotor whirl, critical speed and system stability are discussed in detail. Effects arising from running a rotor through its critical speed are reviewed. Balancing of rigid and flexible rotors is considered with regard to balancing machines, computed calculation of unbalance, and acceptable levels of unbalance. Axial and torsional effects on machine systems are included. Throughout, the important literature relating to each topic is specified, discussed and set in perspective.
