Abstract: The mechanism and characteristic of subsynchronous vibration about turbopump rotor system are explained.The reasons for inducing subsynchronous vibration,which are internal friction,dry friction,and gas dynamic excitation force between turbine blade tip and seal clearance,are discussed.The method reducing subsynchronous vibration is discussed
Key words: Turbine pump;Flexible rotor;Subsynchronous vibration +
