1. Purpose

     The PWS-300 electro-hydraulic servo fatigue testing machine is mainly used for testing the fatigue life of various springs. Different test aids can be replaced as needed, and it can also be used for dynamic and static performance research of various materials and components.

2. Technical parameters

1. Maximum dynamic and static test force: ±300kN

2. Test force indication accuracy: ±1% (2%-100%FS)

3. Column spacing: 760*580mm

4. Workbench size (length×width×thickness): 1260mm×1190mm×240mm

5. Maximum adjustable test space: 1500mm

6. Space adjustment method: hydraulic lifting beam

7. Frequency range: 0.01-20Hz

8. Actuator amplitude: ±150mm (stroke 300mm)

9. Accuracy of displacement indication: ±0.5% (2%-100%FS)

10. Main test waveforms: sine wave, triangle wave, square wave, trapezoidal wave, ramp wave and program control wave, etc.

11. Pumping station: 21Mpa meets: amplitude ±5mm, frequency 8Hz; amplitude ±100mm, frequency 0.4Hz;

12. Control mode: two circuits of test force and deformation; with overload, break protection, automatic shutdown at the end of the test and other functions.
