Abstract

Um die Unwucht der Trommel (1) beim Schleudern messen zu können, sind an der Trommel (1) bzw. am schwingenden System des Geräts Beschleunigungs-Sensoren (7) und ein Winkelgeschwindigkeits-Sensor (8) vorgesehen. Die winkelaufgelösten Geschwindigkeitssignale des Winkelgeschwindigkeits-Sensor (8) werden mit Kalibrationswerten kompensiert, die bei Messungen an einer leeren Trommel (1) gewonnen wurden. Die Messungen der Beschleunigungs-sensoren (7) werden mit Kalibrationswerten kompensiert, welche die Phasenverschiebung der Auslenkung des schwingenden Systems abhängig von der Drehzahl der Trommel (1) widerspiegeln. Durch die Verwendung dieser Kalibrationswerte kann die Messgenauigkeit des Geräts verbessert werden.

Figure imgaf001
In order to be able to measure the imbalance of the drum (1) during spin, acceleration sensors (7) and an angular velocity sensor (8) are provided on the drum (1) or on the oscillating system of the device. The angular resolution velocity signals of the angular velocity sensor (8) are compensated with calibration values obtained from measurements on an empty drum (1). The measurements of the acceleration sensors (7) are compensated with calibration values which reflect the phase shift of the deflection of the oscillating system as a function of the rotational speed of the drum (1). By using these calibration values, the measurement accuracy of the device can be improved.
