Computer Controlled Electro-hydraulic Servo Torsion Fatigue Testing Machine adopts electro-hydraulic servo control technology, which is suitable for static torsion test and dynamic torsion fatigue test of various kinds of synchronizer and various shaft parts. And Computer Controlled Electro-hydraulic Servo Torsion Fatigue Testing Machine  can detect the fatigue properties of materials and components and parts by reciprocating torsion, and can also conduct the fracture surface of the crack in the material inside when the material is fatigued.
