Squeeze-film dampers are means of curing instabilities in rotating-shaft assemblies. Their efficiency depends very much on the condition of the oil, which in turn depends on inlet and outlet arrangements, on damper geometry and on the flexibility of the rotor and surrounding structure. The work discussed in this paper concerns rig investigations in which structural flexibility is included experimentally and comparisons are made between measured and predicted results.
