Aprelevka depot: Response to the operation of vibration analysis system COMPACS-EXPRESS

During operation of the vibration analysis system COMPACS^®-EXPRESS at the depot Aprelevka from 23/10/03 to 25/01/05 the following positive characteristics were noted: reliability, ease of management, the rate of diagnosis, that meets the modern requirements of diagnostic-wheel motor units of electric trains.

The use of vibration monitoring system COMPACS^®-EXPRESS at the depot Aprelevka due to the parallel measurement of vibration from all sensors, allowed to conduct a rapid diagnosis of technical condition of the wheel-motor units of rolling stock for shorter periods of time, which increased the WMU diagnostiс station capacity compared with "manual" devices.

Other advantages of the system COMPACS^®-EXPRESS are:

• archiving of test results in a database for the entire operational period;
• low requirements for the personnel qualification (it is required to install correctly the magnetic sensors in the measuring points);
• high reliability of diagnostic results due to continuous automatic monitoring of the WMU current condition while testing;
• the system allows to detect the hidden defects of bearings and gear reducers, to predict the WMU technical condition for the next period of operation;
• WMU launching from the control panel COMPACS^®-EXPRESS and the test report printout comprising with the results of automatic diagnosis.

During COMPACS^®-EXPRESS operation at the depot Aprelevka were noted the reliability of invalid WMUs detection and the lack of their pass to the operation with defects.
