What is a static fatigue testing machine?
In the fields of industrial manufacturing, materials science, and engineering, static fatigue testing machines are a critical piece of testing equipment used to evaluate the performance and durability of materials or structures under prolonged static loading. With the development of science and technology, static fatigue testing machines have become more and more widely used and have become an important tool for materials research and quality control. This article will introduce in detail the definition, working principle, application fields and recent hot topics of static fatigue testing machines.
1. Definition of static fatigue testing machine
A static fatigue testing machine is a device used to test the fatigue performance of materials or structures under constant load or slowly changing load. Different from dynamic fatigue testing machines, static fatigue testing machines mainly simulate the long-term stress conditions of materials in actual use by applying static or quasi-static loads to evaluate their durability and life.
2. Working principle of static fatigue testing machine
The working principle of the static fatigue testing machine is based on the basic theory of material mechanics. The equipment applies a constant load to the specimen hydraulically, mechanically, or electrically, and records the specimen's deformation, crack growth, or other failure modes. During the test, the equipment will monitor load and deformation data in real time and analyze it through the software.
The following are the main components of a static fatigue testing machine:
| components | Function |
|---|---|
| Load system | Apply static or quasi-static loads |
| sensor | Measure loads, deformations and displacements |
| control system | Adjust load size and loading rate |
| data acquisition system | Record and analyze test data |
3. Application fields of static fatigue testing machine
Static fatigue testing machines are widely used in many industries. The following are its main application areas:
| Industry | Application |
|---|---|
