DYNAMIC CALIBRATION OF THIN-FILM MANGANIN PIEZORESISTANCE GAUGES

This paper discusses the dynamic calibration techniquefor a new kind of thin-film manganin piezoresistance gauge by means of planar impact. The calibration experiments were carried outon a \Phi 130\,mm gas-gun, with PMMA, Cu, and W as the materialsof flyers and targets. The compact pressure was obtained in the range from0.66\,GPa to 25.4\,GPa by the planar impact in differentvelocities. The experimental data are correlated by two kinds of methods,that is, geometry relation calibration and D-u relation calibration. The dynamic calibration and relation curves are obtained.
