A model-based approach for the dynamic calibration of torque transducers

Abstract

The demand for a traceable dynamic torque measurement increased over the last years. Procedures for a dynamic calibration of torque transducers have been developed in an European metrology research project. In the scope of this project, a dynamic measuring device was developed, and the corresponding mechanical modelling, which also includes the transducer under test, was investigated. The dynamic behaviour of the torque transducer is described by the parameters of its model. These model parameters will be identified from measurement data. The model-based approach for the description of the dynamic behaviour of torque transducers and model parameter identification procedures are described in this paper.
