380 B. Damiano Fig. 42.11 Difference in slow-roll–corrected runout values shown in polar coordinates Fig. 42.12 Estimated rotor suspension properties 42.4 Conclusion A method for estimating rotor suspension parameters from runout data has been developed and demonstrated. 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.
