The spring fatigue testing machine uses a motor and a reduction gear to connect with a cam, which drives the connecting rod to perform reciprocating motion, thereby compressing the spring to simulate the stress cycles experienced by the spring in actual use. This type of testing machine is widely used in automotive, aerospace, railway transportation, mechanical manufacturing, and other fields to test the fatigue life of various spiral springs, disc springs, shock absorbers, seal springs, etc. For example, a large spring fatigue testing machine controls the motor operation through an electromagnetic speed control system and uses an eccentric device to drive the connecting rod, causing the reciprocating pressure plate to rise and fall, completing the fatigue test on the spring. This machine features high integration, simple structure, low failure rate, stable and reliable performance, and easy operation.
Implementation standard: JB/T 7796-1995

Working conditions for the spring fatigue testing machine:
1. At room temperature between 10°C and 35°C, with relative humidity not exceeding 80%;
2. Properly installed on a stable foundation or workbench;
3. In a vibration-free environment;
4. Free from corrosive media in the surroundings;
5. The fluctuation of the power supply voltage should not exceed ±10% of the rated voltage;
6. The testing machine's power supply should have reliable grounding; frequency fluctuation should not exceed 2% of the rated frequency.

Precautions for using the spring fatigue testing machine:
1. Under normal usage conditions, the calibration validity period for the indication error of the spring testing machine is one year.
2. When operating the spring testing machine, especially during unloading, do not release suddenly to avoid severe vibrations that could affect the accuracy of the testing machine.
3. Regularly add lubricating oil to the lifting rack and various pressure-feed oil cups of the testing machine.
4. After use, cover the machine with a protective cover to prevent dust from entering.
5. To ensure personal safety, the testing machine should be properly grounded.
