Industrial Automatic Control Systems and Controllers Annotation << Back Computer Methods and Means of Increasing the Efficiency of Power Equipment Vibration Condition Monitoring Reshetov А.А. The necessity to develop computer methods and means of determining the details of the power equipment design (gas compressor units) sensitive to defects is justified. For this purpose, applied mathematical modeling techniques as a cost-effective and developed computational and experimental methods and related software and algorithmic means. In practice, there is a need to develop a means of monitoring and analysis of gas compressor units (GCU) shafting torsional vibration, and taking into account other parameters monitoring of GCU in the creation of the improved model of all existing loads on shafting and elements of the GCU design. According to this model to determine the stress-strain state of the GCU design sites, perform a analysis and identify dangerous areas, where possible birth defects. Proposed methods and means are based on a calculated spectral portraits of the object under diagnosing torsional vibrations (energy modes, energy spectra) over a wide frequency range. That allows to determine the most likely location of defects. The need for power equipment vibration condition monitoring with the help of calculated information about energy modes (spectra) and the standard means of measurement and analysis of torsional vibrations of rotors is shown. This is to prevent accidents and failures of power equipment.
