Electro-hydraulic servo static and dynamic universal testing machine

The electro-hydraulic servo static and dynamic universal testing machine is mainly used for testing the dynamic and static mechanical properties of various materials in various fields such as mechanical metallurgy, aerospace, universities, research institutes, etc. It can also be professionally designed according to user requirements to realize parts and components. Dynamic and static performance tests. The main tests are tensile, compression, bending, low cycle and high cycle fatigue, crack propagation, and fracture mechanics tests.
The operation of the machine is flexible and convenient, the beam is lifted and clamped, and the sample clamping is completed by the electric button automatic hydraulic clamping system. The control system adopts the industrial control chassis with good anti-interference performance as the main chassis, and each function board adopts ISA bus template design, and the maintenance is good. The computer interface adopts virtual panel technology, which is convenient to operate, and can load test waveforms such as sine wave, square wave, triangle wave, oblique wave, combined wave, combined oblique wave and external input acquisition wave in real time.

Performance
Control method: displacement, load, deformation.
Displacement Amplifier: The measurement is divided into 250%, 50%, 20%, and 10%. The accuracy of both directions is ± 0.5%·FS of full scale (20% of full stroke).
Load Amplifier: The measurement is divided into 250%, 50%, 20%, and 10%. The accuracy of both directions is ±1% of the indicated value (20% of full stroke).
Deformation Amplifier: The measurement is divided into four parts of 250%, 50%, 20%, and 10%. The accuracy of both directions of tension and pull is ± 0.5% of the indicated value (from 20% of full stroke).
Computer control: The load computer automatically zeros and shifts gears. Displace the computer to shift gears. The deformation computer is zeroed and shifted. Displacement, load P, I, D computer adjustment. Function generator waveform control. The three control modes of displacement, load and deformation are smoothly switched.
