3 Overview

The torsion machine works according to the principle of torque (even) balance, and can have various structural forms, but all have torque measurement Mechanism, torque application system and clamping device for torsion specimens. Need to give the torsion angle of the sample, it should be equipped Prepare the chuck torsion angle measuring device or torsion meter. Torsional machines are mainly used for the measurement of torsional mechanical properties of materials and finished products, as well as materials and finished products. Performance tests such as torsional damage.

4 Metrological performance requirements

4.1 Torque measuring device metering performance 4.1.1 The torque range is from the lower limit of measurement to the rated value. 4.1.2 The torque measurement performance of the torsion machine of each class shall comply with the technical indicators of Table 1. Table 1 Torque measurement technical indicators of various levels of torsion machines Technical indicators Relative resolution (%) Relative error of indication (%) Reproducibility (%) Zero return error (%FS) Accuracy level 0.5 0.25 ±0.5 0.5 0.5 1 0.5 ±1.0 1.0 1.0 Note. For mechanical torsion machines, the relative error of the indication values with and without the passive needle and the recording device shall comply with the technical specifications of Table 1.
