Investigation of a direct procedure for the dynamic calibration of instruments specifically designed to measure strength - a contribution towards reducing the uncertainty of measurement
In this paper, a prototype of a newly developed dynamic, normal measurement installation for strength is introduced, with which the dynamic properties of strength measurement devices in the frequencies between 20 Hz and 1 kHz can be investigated with great precision. After the precise calibration of the total measurement installation, the procedure was systematically investigated with the swing agitator and additional mass. After the precise analysis of the method of measurement and the measurement installation, several strength measurement devices were examined. To highlight the advantages of the direct method with the swing agitator and additional mass compared to the method using a normal strength absorber, the results achieved are discussed. It is discovered that the swing behaviour of the total system can strongly influence the results in the measurement, and that therefore the method demonstrated in this paper is more suited to frequencies up to 1 kHz.
