AN INVESTIGATION OF THE BEHAVIOR OF FLOATING RING DAMPERS AND THE DYNAMICS OF HYPERCRITICAL SHAFTS ON FLEXIBLE SUPPORTS

Abstract

This report deals with the development of two different analyses for the vibration responses in supercritical shafts: one especially suited for the determination of support impedances (mass, spring, damping coefficients) for minimum vibration response in the criticals; the other for direct vibration response in terms of statically measured shaft defects. The traveling wave concept is extensively discussed. Presented is a preliminary parameter study of the simply supported rotating shaft with one flexible intermediate support subjected to a half sine wave defects distribution. The effects of end masses are studied also. Several conceptual designs of multiring damping assemblies which can accommodate the damping requirements of hypercritical shafts are included in the report.
