Test Bench To Detect Hysteresis on Clutch Disc Assembly  ( vertical-servo)

Main Features
* It mainly consists of basic machine , pneumatic-to-hydraulic system, measuring system and servo control system.
* Adopting pneumatic-to-hydraulic cylinder up working table loading to press out disc assembly, and that amount of 
   clamp load can be obtained by load cell. Adopting torque servo motor under working table can apply positive or 
   negative torque to disc assembly, and that torque transducer is used to test torque value, given rotate angle can 
   be measured by photoelectricity encoder.
* Precise guide loading mechanism.
* Pre-torsion times can be set
* Torsional speed can be set
* Windows operation system, data base function, high accuracy measuring card.
* All measuring results can be stored for query, and its curve displayed on the screen, and to print on A4 paper if 
   need.
Testing Items
* Limiting torque Mmax
* Limiting rotation angle θmax
* Torque hysteresis value Mh in given rotation angle (six points at the most)
* Torsion stiffness Ca in the range of given rotation angle (each three grade in positive or negative position)
* Torque inflexion                         
* Torsion characteristic curve
