Verfahren zur Klemmkraftermittlung an einer wenigstens zwei Komponenten verbindenden mechanischen Fuegeverbindung

WO 2011015332 A2 UPAB: 20110224 NOVELTY - The method involves exciting a mechanical joint connection (FV) to generate oscillations, and capturing the oscillations made by the joint connection due to the excitement. The oscillations of the joint connection are analyzed on the basis of reference oscillation patterns stored in a reference dataset, where known clamping force prevailing in the joint connection to be tested is associated with each oscillation pattern. Oscillation energy coupled in the joint connection leads to formation of oscillation resonance in the joint connection. USE - Method for determining clamping force on a mechanical joint connection e.g. form-fit connection, frictional connection, bolted connection, locking ring bolt and rivet connection i.e. blind rivet connection (all claimed), for connecting two components i.e. clamping bodies, by coupling sound waves into the joint connection. ADVANTAGE - The oscillations of the joint connection are analyzed on the basis of the reference oscillation patterns stored in the reference dataset, where the known clamping force prevailing in the mechanical joint connection to be tested is associated with each oscillation pattern, thus achieving precise determination of the clamping force on the mechanical joint connection in a non-destructive manner and with less effort
