What is a spring fatigue testing machine?
In the fields of industrial manufacturing and materials science, a spring fatigue testing machine is a specialized device used to test the durability and performance of springs during repeated loading and unloading. With the continuous improvement of spring quality requirements in modern industry, the application of spring fatigue testing machines is becoming more and more widespread. This article will introduce in detail the definition, working principle, application fields of spring fatigue testing machine, as well as hot topics and hot content in the past 10 days.
1. Definition of spring fatigue testing machine
The spring fatigue testing machine is a testing equipment that simulates the repeated stress of springs in actual use. By applying cyclic loading, the performance changes of the spring after multiple cycles are tested to evaluate its fatigue life and reliability.
2. Working principle of spring fatigue testing machine
The spring fatigue testing machine is driven by a motor or hydraulic system to apply periodic load to the spring. During the test, the equipment will record data such as the deformation, load size, and number of cycles of the spring, and analyze the fatigue characteristics of the spring through software.
| parameters | Description |
|---|---|
| Loading method | Motor drive or hydraulic system |
| Test frequency | Usually 0.1-10Hz |
| Maximum load | Depending on spring size, up to several tons |
| Data collection | Real-time recording of deformation, load and cycle times |
