Data-driven identification of rotating machines using ARMA deterministic parameter evolution in the angle/time domain
(2020-09-01)
The functional-series angle-/time-varying autoregressive moving-average (AT-FS-ARMA) model was used to model and analyze vibration-based signals from internal combustion engines. This approach is derived from the formulation ...
A method for evaluating spindle rotation errors of machine tools using a laser interferometer
(2008)
This paper presents a method for assessing radial and axial error motions of spindles. It uses the Hewlett Packard
5529A laser interferometer. The measurement is made using reflection directly from a high-precision sphere. ...
Prediction of failures in rotating machines by vibration spectral analysis

Expert system to detect incipient fauts in rotating machines using fuzzy logic and virtual instrumentation
(2012)
This paper refers to the design of an expert system that captures a waveform through the use of an accelerometer, processes the signal and converts it to the frequency domain using a Fast Fourier Transformer to then, using ...
Time-frequency analysis combining wavelets and the envelope technique for fault identification in rotary machines
(2013-03-18)
Nowadays the method based on demodulation by envelope finds wide application in industry as a technique for evaluation of bearings and other components in rotating machinery. In recent years the application of Wavelets for ...
