Structural characteristics:

1. High strength loading frameworkTypically, it is a four column or double space structure that provides rigidity and stability.

2. Servo hydraulic system：

• High flow hydraulic sourceProvide stable and high-pressure hydraulic oil.

• Servo actuator cylinderCore execution component that outputs high-frequency and high amplitude dynamic tension.

• servo valveAccurate control of oil flow direction and flow rate to achieve precise load control.

3. Control system and measurement system：

• servo controllerImplement closed-loop control of load or displacement.

• High precision force sensorDirectly measure the dynamic tensile force applied to the specimen.

• displacement sensorMeasure the stroke of the actuator cylinder.

• strain gaugeStick it on key parts of the anchor plate to monitor stress changes in real time.

4. Special anchor fixtureUsed to fix anchor plates and tension steel strands to ensure alignment.

5. Computers and SoftwareSet test parameters (average load, load amplitude, frequency, number of cycles), display real-time load time curve and strain data, and automatically shut down when the specimen fractures or reaches the set number of cycles.

6. Heavy duty safety protection deviceTo prevent fragments from breaking and flying out of the test piece, ensuring the safety of personnel and equipment.
