High and low temperature spring fatigue testing machine

Features of High and low temperature spring fatigue testing machine

1. Mechanical loading, using the traditional crank connecting rod mechanism, electromagnetic speed regulation motor drive, using the energy storage method of the flywheel, to ensure the uniform stability of the loading and the reliability of the operation, so that the entire alternating stress forms a good sinusoidal waveform. In addition, it also has a spring pre-adjustment device (electric adjustment method), an amplitude adjustment device (manual adjustment method), etc.

2. It is composed of speed increasing device, lead screw and guide part.

3. Electromagnetic speed-regulating motor drive.

4. It is composed of computer data acquisition and processing system, counter, speed control device, force measurement system and displacement measurement system. Through various signal processing, it realizes functions such as display and control, and records the number of tests, test frequency, test force, etc. displacement etc. And real-time display of force-deformation curve, force-time curve, deformation-time curve, etc. Simple adjustment and stable performance.

5. Using WIN2000/XP Chinese operating platform, the format of the test report can be output in Word or Excel format.

6. Automatic shutdown, overcurrent, overvoltage, overspeed protection devices, etc. when the set times and time are reached.
