When monitoring turbine blade vibration, the turbine rotor vibration is measured using at least one rotor vibration sensor located on at least one turbine bearing. The signal obtained is preprocessed by converting it from the time domain to the frequency domain (preferably by a discrete Fourier transform), the wide band spectrum noise level of signal is suppressed (preferably by liftering the signal cep strum) and the variance of the wide band spectrum signal noise is suppressed (preferably by averaging the liftered spectra of the signal). Subsequently, the components of the blade vibration in the preprocessed signal are identified. The identification includes the process of thresholding the preprocessed signal and clustering the components from the thresholding. The identified blade vibration components are then monitored for the magnitude of deviation in frequency and/or amplitude of at least one identified component from its nominal state.

Method of manufacturing hybrid parts consisting of metallic and non-metallic materials at high temperature
This invention generally relates to a method of manufacturing hybrid parts comprising metallic and non-metallic materials at high temperature. During the method, a hollow metallic feedstock heated to a temperature in the austenite region may be placed in a die and filled with a non-metallic material in a viscous condition, after which the feedstock in the die is formed and then controlled-cooled to cause hardening of the non-metallic material in the region of contact between the metallic and non-metallic material. Afterwards, the semi-finished product is removed from the die and cooled to room temperature. The rate of cooling may be adjusted to generate compressive stress in the surface layer of the non-metallic material, which reduces the risk of cracking.
