| Abstract: | In this paper, the three methods of Central-Quality, Beam Element and Finite Element are used to study the Dynamic Characteristics of Rotor-Bearing System. The numerical results indicate that the Finite Element way can be used to analyze the inherent frequencies and modes better whereby providing the design base for Rotor-Bearing System as well as creating the theoretical analysis foundation for Rotor-Bearing System supported by oil-film and magnetic forces. |
