IDENTIFICATION OF MODEL PARAMETERS OF A PARTIALLY UNKNOWN LINEAR MECHANICAL SYSTEM FROM MEASUREMENT DATA

Leonard Klaus

Abstract

The dynamic calibration of torque transducers requires the modelling of the measuring device and of the transducer under test. The transducer’s dynamic properties are described by means of model parameters, which are going to be identified from measurement data. To be able to do so, two transfer functions are calculated. In this paper, the transfer functions and the procedure for the model parameter identification are presented. An example shows results of the parameter identification.
