A method of evaluating an operating state of a flow machine includes measuring, in the operating state of the flow machine, a first force component of a bearing force acting on a rotor axle along a first direction using a first force sensor, the first direction lying perpendicularly to the axial direction, measuring a second force component of the bearing force in a second direction using a second force sensor, the second direction lying perpendicularly to the axial direction and being simultaneously perpendicular to the first direction, a resulting force being formed from the first force component and the second force component, preparing a frequency spectrum of the resulting force using a frequency analysis, comparing the frequency spectrum with a reference spectrum, and evaluating an operating state at a predefined operating state of the flow machine. |
