Vibrations of Rotors Supported on Nonlinear Bearings

Rotordynamic Stabilization of Rotors on Electrodynamic Bearings

Nonlinear vibration signature analysis of a rotor supported ball bearings

The dynamic behaviour of a high speed balanced rotor supported on deep groove ball bearings (SKF-6205) has been studied by numerically simulated results. Since, internal radial clearance (IRC) is inevitably present in all class and types of bearing, in this paper it (IRC-C3) is considered as main source of nonlinearity with speed as control parameter. The complex mathematical model simulates no...

A rotary microactuator supported on encapsulated microball bearings

The development of a rotary microactuator supported on encapsulated microball bearings and driven by electro-pneumatic actuation is reported. The encapsulated bearing provides full support to an encased rotor, while an electro-pneumatic thrust balance is used to minimize rotor normal load. By minimizing normal load, bearing friction is reduced leading to increased speed and performance. Experim...
