Abstract


This paper introduces steam-turbine generator set action mechanism of rubbing fault happens. Through the simulation computation and simulation test, the dynamic rotor rubbing fault vibration characteristics. To Jeffcott rotor for action rubbing of the simplified model, the establishment of a system of differential equations, the simulation calculation and analysis the damping and stiffness parameters change on rubbing effect of vibration. Rotor rubbing fault test simulates the rotor in normal operation, mild rubbing and serious rubbing process, a full test and analysis of data processing, access to rubbing rotor vibration characteristics of rotor movement rubbing fault diagnosis to provide accurate and reliable basis.
