Abstract

This paper discusses the dynamic calibration technique for a new kind of thin-film manganin piezore-sistance gauge by means of planar impact.The calibration experiments were carried out on aΦ130 mm gas-gun, with PMMA,Cu,and W as the materials of flyers and targets.The compact pressure was obtained in the range from 0.66 GPa to 25.4 GPa by the planar impact in different velocities.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.
