What is a constant stress testing machine?
The constant stress testing machine is a professional equipment used to test the mechanical properties of materials. It is mainly used to test the deformation, fatigue, creep and other properties of materials under constant stress conditions. It is widely used in aerospace, automobile manufacturing, building materials and other fields, and is an indispensable tool in scientific research and industrial production. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of constant stress testing machines.
1. Definition of constant stress testing machine
The constant stress testing machine is a testing equipment that can maintain constant stress loading. By accurately controlling the loading force or displacement, it can simulate the stress of the material in actual use. It can test the performance changes of materials under long-term or short-term stress, providing data support for material research and development and quality control.
2. Working principle of constant stress testing machine
Constant stress testing machines apply force through servo motors or hydraulic systems, and monitor force and displacement in real time through sensors. The control system adjusts the loading force according to the set value to ensure constant stress. During the test, the equipment will record data such as material deformation and fracture, and generate a report through software analysis.
3. Application fields of constant stress testing machine
Constant stress testing machines are widely used in many industries. The following are the main areas:
| field | Application scenarios |
