DETERMINATION OF MODEL PARAMETERS FOR A DYNAMIC TORQUE CALIBRATION DEVICE

Leonard Klaus, Thomas Bruns, Michael Kobusch

Abstract

For the dynamic calibration of torque transducers, a calibration device has been developed. This paper describes the model of the measuring device and methods for the determination of its model parameters. The modelling of the calibration set-up is required for the identification of the corresponding model parameters of the torque transducer under test. These parameters describe the transducer's dynamic behaviour. Measurement methods and devices for the determination of mass moment of inertia and torsional stiffness are explained. This research is part of EMRP JRP IND09 - "Traceable Dynamic Measurement of Mechanical Quantities".
