It is mainly used to test mechanical properties of various materials and components under
the dynamic and static load. It includes tensile, compression, bending , shear and fatigue test.
Feature:
1.Host rack has high stiffness, high natural frequency funciton without backlash.it is suitable
for long cycle of stress and fatigue life test.
2.Using integration design of actuators, servo valves, displacement sensor, it ensures high
precise, fast response.
3.Hydraulic-servo oil source use design of leak and the quiet technique, which ensure leak-free ï¼low noise during operation.
4.the electro-hydraulic servo valve in wide speed range and computer compose full-digital closed loop control system, can realize precise measurement and control test for the
entire process of testing. This system has three control modes such as force and displacement,
deformation.
5.Test software work under windows 2000/XP, operate easily. Display Dynamic test waveforms
and complete the corresponding data,the test condition and result will be automatically stored .it will automatically display, print curves and test report
