Attenuation of Bearing Transmitted Noise. Volume 2

Abstract

A study is made of the attenuation of the force transmitted by an unbalanced rotor. The attenuation is achieved by a flexible bearing support. An analysis is presented of the unbalance vibrations of a flexible, symmetrical, two-mass rotor supported in fluid film bearings which in turn are mounted in flexible supports. The fluid film in the bearings possesses both flexibility and damping. The analysis takes into account both static and dynamic rotor unbalance and gives results for the rotor amplitudes and the transmitted force as functions of the system parameters. The analysis has been programmed for a digital computer and a description of the two computer programs is included. Numerical results have been obtained and are summarized in 24 design charts.
