Servo hydraulic fatigue testing machine
±25kN ~ ±2000kN 0.01~50Hz HDT-A series
Equipment overview:This machine is mainly used to test the dynamic and static mechanical properties of metal, non-metallic materials and components, elastomers, shock absorbers.The tensile, compression, bending, low cycle and high cycle fatigue, crack propagation, fracture mechanics test are completed.It can be equipped with high temperature furnace, low temperature box, corrosion box, etc., to realize the mechanical test of sample in different environment.
Performance characteristics:
The enclosed type t-frame structure has a large frame stiffness, no reverse clearance and good stability.Moving beam lifting, locking and sample clamping are all convenient and flexible by button operation.The servo actuator is mounted on the actuator, and the piston design is adopted in the bidirectional acting oil cylinder, which is convenient and stable.Meet the standard:
