摘要： A method of analysing tachometer and vibration response data from an apparatus having one or more rotary components is provided. The method comprises the steps of: providing vibration response data and corresponding tachometer data from the apparatus for a period over which a rotary component of the apparatus varies in rotational speed, the tachometer data being for that component; repeatedly performing at intervals throughout the period the sub-steps of: determining a forcing frequency of the component from the tachometer data and a corresponding vibration response frequency of the apparatus from the vibration response data, comparing the forcing and vibration response frequencies to determine the relative phase difference between the frequencies, and determining the corresponding amplitude of the vibration response from the vibration response data; and plotting the relative phase differences and vibration amplitudes on a polar diagram. The plot trajectory is characteristic of the behaviour of the apparatus over the period.

摘要： A method of monitoring vibration amplitude and frequency in a rotary machine by spectral analysis of the vibration data. Vibration amplitudes are recorded as a function of rotation speed and of frequency and the data is analyzed to estimate a noise floor amplitude threshold for each of a plurality of different speed and frequency sub-ranges. Thus the noise floor varies for different speeds and frequencies. On the basis of training data known to be normal speed-frequency areas which contain significant spectral content in normal operation are deemed "known significant spectral content", so that during monitoring of new data points which correspond to significant vibration energy at speeds and frequencies different from the known significant spectral content can be deemed "novel significant spectral content" and form the basis for an alert. The estimation of the noise floor is based on a probabilistic analysis of the data in each speed-frequency area and from this analysis an extreme value distribution expressing the probability that any given sample is noise is obtained. For any new data sample the probability that it corresponds to noise can be read from this extreme value distribution, and an index calculated from this probability, with this technique being effective to detect higher order harmonics not usually detectable in vibration spectra.

摘要： One embodiment of the present invention includes an internal combustion engine with a turbocharger. The turbocharger includes a compressor with an outlet coupled to an intake of the engine and a turbine coupled to an exhaust manifold of the engine. A a turbocharger speed estimate is determined from engine speed and a ratio between inlet and boost pressure for the compressor. The turbocharger speed estimate is further adjusted as a function of compressor boost pressure variation with time.
