Title: Experimental determination of lateral vibration of the 708 MVA Westinghouse vertical hydro generators at Grand Coulee Dam, Washington

Abstract

The damped rotor bearing system of large vertical shaft systems presents special problems for high speed storage installations. The results of the first test of its kind have given experimental data contributing to this technology. Synchronous and non-synchronous vibrations were found to contribute to runout loading. Measurements on the pivot pad hydrodynamic bearings gave stiffness characteristics. Measurements showed that balancing the rotor reduced vibration levels. 1 ref.
