Vibration Signal Forecasting on Rotating Machinery by means of Signal Decomposition and Neurofuzzy Modeling

Signal decomposition by means of classification of spectral peaks

In extending previous work on detecting transient spectral peaks we here investigate into the distinction between sinusoidal and noise components by means of classification of spectral peaks. The classification is based on descriptors derived from properties related to time-frequency distributions. In contrast to existing methods, the descriptors are designed to properly deal with non-stationar...

Vibration Signal Filtering Algorithm Based on Singular Value Subspace Decomposition

In the area of fault detect for rotating machinery, the vibration signal should be filtered before parameter detection and quality evaluation. For the filtering of the vibration signal, it is needed to keep the linear phase characteristics while obtaining good filtering effect. Aiming at the filtering problem of vibration signal, a filtering algorithm based on singular value subspace decomposit...

Kinetics analysis of electrophoretic deposition using small signal and large signal modeling, Case study: Nano-Mullite suspension

Having sufficient and accurate understanding about kinetics of phenomena, could be an important reason for further technological progresses. Finding a white-box mathematical model for weight vs. time curves of Electrophoretic Deposition (EPD) using large and small signal analysis has been studied thoroughly in the present investigation. Weight-Time curves of nano-Mullite suspension have been tr...

Adaptive time–frequency decomposition for transient vibration monitoring of rotating machinery

Monitoring the vibration behaviour of large rotating machinery is an effective way to reduce production losses and enhance safety, efficiency, reliability, availability and longevity in manufacturing processes. As large rotating machinery is increasingly employed in continuous operations at high speeds and with heavy loads, the vibration behaviour of the rotor systems is more and more complex. ...
