摘要
介绍了以飞片平面撞击标定某新型锰铜压阻计的过程及方法.标定在Φ130 mm轻气炮上进行,采用有机玻璃,Cu和W 3种材料为飞片和靶板材料,实现不同速度下的同种材料平面正撞击,获得0.66～25.4 GPa范围的入射压力,并利用几何修正和D-u关系修正两种方法对结果进行了修正,给出了标定结果以及拟合曲线.
This paper discusses the dynamic calibration technique for a new kind of thin-film manganin piezoresistance gauge by means of planar impact. The calibration experiments were carried out on a Ф130 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.
