摘要：A magnetic stiffness matrix was derived to express the energy of air-gap magnetic field of generator rotor,and an eight-parameter model and Muszynska model were used to simulate the seal effect of turbine impeller.A shaft system model was developed with consideration of the vibration sources in the magnetic field and the hydraulic seal.By adopting these models,sensitivity analysis was conducted for the responses of critical speed to various parameters of magnetic field,seal,journal stiffness and outer diameter.This study offers references for dynamic design and operation of generator set.
