Method applied for increasing reliability of diagnostics of axle equipment of wheel-motor units in electric trains

Print

To increase diagnostic reliability providing an objective assessment of equipment’s condition is an urgent task. The paper includes the estimation of errors for wheel-motor unit axle equipment diagnostics carried out while testing wheel-pairs at various rotation frequencies.

The main diagnostic task is to recognize condition of assemblies and machines and classify them as faultless or faulty, which is related to risks of false alarm or defect skipping. Utilization of any of the diagnostic methods may lead to such errors as defect skipping or false alarm.

A defect skipped during a rolling stock operation may lead to the destruction of an assembly, and that may cause not only an expensive unscheduled repair, failures in train movement schedule, but also a hazard or an accident. False alarm may lead to additional repairs at the assemblies that do not require any maintenance, which can make the condition even worse, thus, reducing the operational readiness of the rolling stock.

The paper is aimed at increasing reliability of diagnostics with minimum costs of testing.
