Abstract

Determining the dynamic characteristics of rotor suspensions is needed to make accurate predictions of rotor behavior. If direct measurements are unavailable, a method for estimating them is needed. This paper describes a method for estimating suspension characteristics from rotor runout data measured by proximity probes in a rotor test stand. Comparison of measured critical speeds with values predicted using the estimated rotor suspension parameters for a test rotor show good agreement, indicating that the method is valid.
