N2 - The research explores rotor dynamics characteristics and dynamic responses of Sodium bearing rotor coupled system fast reactor two-circuit main loop liquid sodium pump system in the nuclear power station. Natural frequency and vibration modes are given, vibration amplitude at the key point of support position are extracted. Through the analysis, rotor-dynamic properties and performances of the rotor system are given. With regard to different operating and initial conditions, the rotor-dynamic characteristics are investigated. Extreme operation conditions are also analyzed. Analysis shows that the structure design of sodium bearing as well as the bearing-rotor coupled system are reasonable and reliable, which can fully meet the technical requirements. Results indicate that it has certain guidance for the design of special engineering bearing-rotor system.
