Effects of bearing clearances, or "dead bands," on bearing loads and rotor stability in turbopumps examined in a 194-page report. Relatively simple mathematical force model for analyzing effects highlighted. Report shows nonlinear characteristics resulting from bearing dead bands have significant effect on dynamics of turbomachinery and not ignored as in the past.
