What is a pressure universal testing machine?
In the fields of modern industrial production and scientific research,Pressure universal testing machineIt is an important equipment widely used in testing the mechanical properties of materials. It can conduct various mechanical tests such as tension, compression, bending, and shearing on various materials such as metal, plastic, rubber, and composite materials to evaluate key performance indicators such as strength, elasticity, and plasticity of the material. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of pressure universal testing machines.
1. Definition of pressure universal testing machine
A pressure universal testing machine, also known as a universal material testing machine, is a device that tests the mechanical properties of materials by applying controllable force or displacement. It usually consists of a loading system, a control system, a data acquisition system and a software analysis system, which can simulate the stress of materials in actual use and provide accurate test data.
2. Working principle of pressure universal testing machine
The working principle of the pressure universal testing machine is based on Newton's third law. It applies force to the sample through a hydraulic or electric drive system, and simultaneously measures the force value and deformation in real time through sensors. The test data is processed by computer software to generate key parameters such as stress-strain curve, tensile strength, and yield strength. The following is its core workflow:
| steps | Description |
|---|---|
| 1. Specimen installation | Fix the material to be tested in the fixture of the testing machine to ensure uniform stress. |
| 2. Loading force | Force is applied via a hydraulic or motor drive system to control the loading rate. |
| 3. Data collection | The sensor records the force value and deformation in real time and transmits them to the computer. |
| 4. Data analysis | The software generates test reports, including stress-strain curves, break points, etc. |
3. Application fields of pressure universal testing machine
Pressure universal testing machines are widely used in the following fields:
| Industry | Application scenarios |
|---|---|
| Manufacturing | Test the mechanical properties of metal, plastic and other materials to ensure product quality. |
| construction project | Evaluate the compressive and tensile strength of construction materials such as concrete and steel bars. |
| Scientific research institutions | Research the properties of new materials and optimize material formulas. |
| Automobile industry | Test the durability of components and improve safety performance. |
4. Comparison of popular models in the market
The following are the mainstream pressure universal testing machine models on the market in 2023 and their performance comparison:
| Model | Maximum load | Accuracy | Applicable materials |
