本文分析了MTS 632.68C—01高温拉一扭引伸仪测量扭转应变信号的基本工作原理,并据此原理推导出在非标定状态下,其输出扭转应变信号的修正公式及简化计算式。从而大大扩展了该引伸仪的使用范围。
In this paper, the basic working principle of MTS 632.68C-01 high temperature tensile torsion extensometer for measuring torsional strain signal is analyzed. Based on this principle, the correction formula and simplified formula of output torsional strain signal in non-calibrated state are deduced. Thus greatly expanding the scope of use of the extensometer.
