Blade loss simulation of multi mass rotor model with nonlinear tilt pad journal bearings Conference Paper uri icon

abstract

  • The prediction of rotor vibrations due to large imbalance requires nonlinear solution of the supporting bearings. This discussion presents a methodology and results for the effects of large, sudden imbalance on the response of a multi mass rotor model supported on tilt pad journal bearings. For a given imbalance, response is obtained for rotor speeds below, above and at the rotor natural frequency. The given imbalance response is also compared with two other methods used for predicting the transient response of a rotor bearing system.
