Smart Integrated Bearing (SIB)

This page introduces the concept of using a smart integrated bearing as a unique load carrying element, which is able to effectively carry the load by a journal bearing integrated with an electro-magnetic actuator (flooded in oil) that is able to control the rotor behaviour.

The electro-magnetic actuator is used to control both the oil whip instability in the journal bearing as well as single plane and two plane unbalance in the rotor.

The theory is presented, and numerical and experimental results are presented that illustrate the success of the SEMAJIB and algorithms developed to control rotor vibrations.
