Abstract: Unbalance is the principal cause of excitation of lateral vibrations of rotors and generation of the forces transmitted through the rotor supports to the foundations. These effects can be significantly reduced if damping ...

Abstract: Flexure pivot® journal bearings (FPJBs) have typically been used in small high-speed applications such as integrally geared compressors and multistage high-speed compressors, where the temperature management and the ...
