| Abstract: | In order to study the fault mechanisms of rotating machinery,the vibration of a 200MW steam turbine generator in a power plant is measured during running down the generator.Measured results indicate that there exist complex vibrations and various faults.The nonlinear faults and multi-faults are also obvious in the rotor system.In this paper,the fault characteristics and fault mechanisms of the rotor system are analyzed based on the measured vibration data.These measured data and analyzed results are the important guidance in the dynamic design,modification,condition monitoring and operation management of rotating machinery. |
| Keywords: | rotating machinery vibration measurement fault phenomena fault mechanism |
