1.Introduction and application-torsion testing machine

l  It is applicable to static mechanical properties test for metallic, nonmetallic materials and various construction member, like transmission shaft and semi-axis;

l  Adopting horizontal structure, computer screen display, digital data acquisition and control system as well as fully digital AC servo system;

l  Adopting planetary cycloid pinwheel speed reducer to drive, with features of even loading, stability, without impact, accurate data acquisition.

l  If equipped with special grips, it can perform torsional force, torsional angle, and angle stiffness for metals and rubber cohesive layers.

l  Parameters modulus G, proof strength,non-proportional torsion τ_p,upper yield strength τ_eH, lower yield strengthτ_eL, torsional strength τ_m,etc can be measured and calculted on software automatically.
