1.Introduction and application-torsion testing machine
 it is applicable to static mechanical properties test for metallic, nonmetallic materials and various construction member, like transmission shaft and semi-axis;
 adopting horizontal structure, computer screen display, digital data acquisition and control system as well as fully digital ac servo system;
 adopting planetary cycloid pinwheel speed reducer to drive, with features of even loading, stability, without impact, accurate data acquisition.
 if equipped with special grips, it can perform torsional force, torsional angle, and angle stiffness for metals and rubber cohesive layers.
 parameters modulus g, proof strength, non-proportional torsion ïp, upper yield strength ïeh, lower yield strengthïel, torsional strength ïm, etc can be measured and calculted on software automatically.
