Abstract
Turbine is the core component of a turbo pump launching system.To reveal the effects of rotor system parameters on vibration of the turbine rotor system,the Lagrange equation is adopted to establish the differential equations of motion for the transient operation of the turbine rotor by considering the gyroscopic effect,support stiffness,support damp and structural damping of the system.The differential equations are solved,the effects of the parameters,such as unbalanced mass and acceleration,on rotor vibration are analyzed,hence the affecting rules of these parameters on rotor vibration are obtained.It is suggested that the unbalanced mass should be reduced as far as possible in engineering,and the gradient acceleration or positive exponential acceleration should be used to reduce vibration of the turbine.This study may provide a reference for the dynamics design of turbine rotor.关键词
