What is an electronic fatigue testing machine?
In the fields of industrial manufacturing, materials science and product quality testing, electronic fatigue testing machines are vital equipment. It evaluates the fatigue life and durability of materials by simulating cyclic loading in actual use. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of electronic fatigue testing machines.
1. Definition of electronic fatigue testing machine
Electronic fatigue testing machine is a kind of testing equipment that uses an electronic control system to repeatedly load and unload materials or components. Through high-precision sensors and computer systems, key data such as stress-strain curves and fatigue limits of materials can be accurately recorded.
2. Working principle
The electronic fatigue testing machine mainly consists of the following parts:
| components | Function |
|---|---|
| Loading frame | Provide mechanical support and force-exerting structures |
| Servo motor | Driven loading system generates cyclic loads |
| force sensor | Measure applied force in real time |
| Displacement sensor | Measure the deformation of the specimen |
| control system | Set test parameters and collect data |
3. Main application areas
