Impact Response of Rotor-bearing System to an Arbitrary Excitation of Pedestals : 2nd Report: Experiments on Rotor Vibration due to Various Types of Excitation

概要

論文の詳細を見る
Vibration experiments on a rotor-bearing system were systematically executed in four different types of excitation and the results were discussed with respect to non-linear effects of the bearing oil film. Not the obvious non-linearity of the unbalance response, but linearity to a large amplitude was shown by the corresponding alternative force and the static force acting on the rotor itself, and the non-linear solution and the static deflection were compared.
