What is a spring fatigue life testing machine?
In the fields of industrial manufacturing and materials science, spring fatigue life testing machines are important testing equipment used to evaluate the durability performance of springs during repeated loading and unloading processes. With the continuous improvement of product quality requirements in the manufacturing industry, the application of spring fatigue life testing machines is becoming more and more widespread. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of spring fatigue life testing machines.
1. Definition of spring fatigue life testing machine
The spring fatigue life testing machine is an instrument specially used to test the fatigue life and performance of springs under cyclic loading. By simulating the repeated stress of the spring in actual use, the testing machine can record key data such as the number of fatigue fractures and deformation of the spring to evaluate its reliability and service life.
2. Working principle of spring fatigue life testing machine
The working principle of the spring fatigue life testing machine mainly includes the following steps:
1.Load device: Cyclic loading is applied to the spring through a motor or hydraulic system.
2.Data collection: Real-time monitoring of spring displacement, load and cycle times through sensors.
3.data analysis:Transmit the collected data to the computer system for fatigue life analysis and curve drawing.
3. Application fields of spring fatigue life testing machine
Spring fatigue life testing machines are widely used in the following fields:
1.automobile manufacturing: Test the durability of automobile suspension springs, clutch springs, etc.
2.Aerospace: Evaluate the performance of aircraft landing gear springs and high-precision instrument springs.
3.electronic equipment: Testing micro springs used in mobile phones, computers and other equipment.
4.medical device: Verify the reliability of springs in surgical instruments and implantable devices.
4. Comparison of popular spring fatigue life testing machine models in the market
| Model | Maximum load | frequency range | Applicable spring type | price range |
