Abstract: The movement is rubbing rotating machinery of the stator and rotor contact between the failure of a phenomenon. With the large turbogenerator in a high-performance, high efficiency and the development parameters, static and dynamic part of the radial small space, rubbing the possibility has increased, the unit has become a common fault. Rubbing will turn, the static of space increases, the bearings support wear, broken or even the whole unit leaves the rotation of the damage to failure. Therefore, in-depth understanding of rubbing the vibration and development mechanism, timely and accurate diagnosis and early forecasting unit shaft move rubbing failure, reasonable measures to deal with, no doubt will be more effective in raising the safety of the crew and the economy, to prevent Major accidents.
Key words: Turbine, rubbing movement, vibration characteristics, fault diagnosis
