1. Testing machine host: The columns, base and beams form a closed frame structure. The frame has high rigidity, no backlash and good stability. The outer surface of the column is electroplated with hard chromium, and the servo actuator (cylinder) is placed underneath. It adopts a double-acting cylinder piston design, and the sample clamping adjustment is convenient and flexible.
2. Hydraulic servo pump station: It adopts leak-free silent technology, with stable pressure output, no fluctuation, low noise, good heat dissipation effect, high filtration accuracy, automatic protection for pressure overload and oil temperature overheating.
3. Control method: PID closed-loop control of force, displacement and deformation, and can realize smooth and disturbance-free switching of any control mode.
4. Test software: It is suitable for operation and control system under the Windows test platform. It can control the test system to complete various dynamic and static mechanical performance tests, such as metal tensile, compression, bending, low cycle and metal fracture mechanics tests. And independently complete various test management, data storage, test report printing and other functions.
5. Test waveforms: sine wave, triangle wave, square wave, random wave, sweep wave, combined waveform, etc.
6. Protection function: It is equipped with alarm and shutdown functions such as oil circuit blockage, over-temperature, low liquid level, hydraulic system overload, motor overheating, preset fatigue times, specimen breakage, etc.
