Abstract
A method of evaluating a wear state of an assembly of a flow machine, in particular, of a bearing arrangement of a pump or turbine. For determining a wear characteristic, a mechanical query signal having a pre-definable signal shape is generated by a signal generator and a response signal generated from the query signal is detected using a sensor in contact with the assembly. The response signal is varied in dependence on a variation of a physical operating value of the assembly in accordance with a characteristic pattern, the wear characteristic is determined from the variation of the response signal and the wear state is evaluated using the wear characteristic.
