A dominant source of vibration in geared rotor systems are the gear mesh dynamic transmission error (TE) parameters. These include the static TE, the mesh stiffness and damping, and the gear runout. One needs to know additionally these dynamic parameters along with the gear macro-geometry (for examples, the number of teeth, pitch circle diameter, pressure angle, and tooth geometries), load and rotating speed, for the vibration-based diagnosis of geared rotor power transmission units.enGeared-rotor SystemTransmission ErrorRun-outsMultiple FaultsFull-spectrumIdentificationThesis
