Critical speeds of a rotating system with flexible, damped supports.

Abstract

Ar experimental and theoretical analysis of a rotating system with flexibly supported, viscously damped bearings is described. The. theoretical development is ba«ed on the differential equations of motion of the mass of the rotor and the two shaft bearings. Tests were conducted and compared with calculated response of the system. Results indicate fair agreement The discrepancies are attributed to limited accuracy of test measurements and/or erratic operation of the viscous damping dashpots.
