Impeller for the determination of the oscillation behavior of the impeller blades, test stand for the determination of the oscillation behavior of the impeller vanes and a method for determination of the vibration behavior of the impeller blades

摘要

The present invention relates to a wheel for the determination of the oscillation behavior of the impeller blades, with a plurality of on a hub (11) of the impeller (2) positioned impeller blades (9).According to the invention, at least one coupling member (10) between two adjacently positioned impeller blades (9) is provided, wherein the provided for the measurement rotor blade (9) is neither at a first side surface (12) of the rotor blade is still at a second side surface (13) of the rotor blade has a coupling element (10).
