Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Information technology of increasing the efficiency of vibration diagnostics of power equipment RESHETOV А.А. The necessity to develop 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 hardware. 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. As the criteria of the most probable arising of defects it is suggested to use high energy intensive levels (energy modes, energy spectra) of units at the corresponding natural frequencies of dynamic model of the object under diagnosing. The need to determine in advance of hazardous areas of the power equipment shafting where possible the birth defects in the transient process is shown. Keywords: information technology, methods, means, efficiency, vibration diagnostics, power equipment, defects, torsional vibrations, energy modes, energy spectra.
