Impact Response of Rotor-bearing System to an Arbitrary Excitation of Pedestals : 1st Report : Comparison of Linear Analysis with Experiment

概要

論文の詳細を見る
Assuming linearized coefficients of oil film, impact response analyses of rotor-bearing system subjected to an arbitrary excitation of pedestals were made and an experiment was executed. The analyzed characteristics were in good agreement with experimental ones, in reference to two eigen values with different whirl directions and impact response by the forces generated on the exciting table. Though the non-linearity of oil film is expected in the case of steady state response by the force such as the rotor unbalance, the linearity of impact response is retained up to a considerably large amplitude of rotor.
