3 Overview
3.1 Purpose
Reverse torsion measuring mechanical properties of materials and finished products is mainly used, it can also be used for materials and finished products
Reverse destruction performance tests.
3.2 Principle structure
Twisting machine according to torque (even) the principle of balance work, can have a variety of structural forms, but shall have torque measurement
Institutions, and the holding torque is applied to the system by means twisting the specimen. Need to give a sample torsion angle twisting machines should be equipped with clip
Head angle measuring device or reverse the count.
