Vibroacoustic analysis is put to use in order to increase reliability and objectivity of condition monitoring of all bearings and reduction gear of wheel motor units of ER-2 electric multiple unit.
The COMPACS®-EXPRESS system ensures evaluation of current technical condition and prediction of future technical condition of the elements of wheel motor unit by the results of measurement of vibration parameters, determines quantitative characteristics of physical quantities used as diagnostic features, displays them on the screen as a special board which shows quantitative and qualitative characteristics of the feature.
At the same time built-in expert system displays on the screen text and graphical information on a technical condition of wheel motor unit according to the test results. A printing device records this information, and the test results are automatically archived in the form of test reports.
Implementation of the COMPACS®-EXPRESS system for vibration analysis enables to improve the quality of repair and reliability of electric stock.
