【Abstract】 The bearing design and stability of rotor bearing system for a 350MVA pulse generator have been investigated in this paper.The static and dynamic performances of the bearing have been calculated with a program based on the finite difference characteristic vector method.The stability of rotor bearing system was calculated by means of transfer matrix eigenvalueequation solution method.A elliptic journal bearing has been adopted.Through adjustment of parameters combined with a lot of calculations for the bearing performance and rotor bearing stability,the designed bearing can meet the requirements of the generator.更多还原
