What is a bending and compression testing machine?
The flexural and compressive testing machine is a testing equipment widely used in the fields of building materials, metal materials, plastics, rubber and other fields. It is mainly used to test the flexural strength (bending strength) and compressive strength of materials. It is an important tool in engineering quality inspection, scientific research experiments and production control, and can provide accurate data support for material performance evaluation. The following will introduce the flexural and compressive testing machine in detail from the aspects of structure, principle, application and popular technology trends.
1. Structure and working principle of the bending and compression testing machine
Flexural and compressive testing machines usually consist of the following core parts:
| Component name | Function description |
|---|---|
| Load system | Driven by hydraulics or motors, vertical or lateral pressure is applied to the specimen. |
| control system | Use PLC or microcomputer control to adjust the loading speed and pressure value. |
| sensor | Monitor force, displacement and other parameters in real time and feed them back to the data processing system. |
| Fixture device | Replace different fixtures according to test requirements (bending resistance/compression resistance). |
Its working principle is to calculate the strength index of the material by applying gradually increasing pressure to the sample until the material breaks or deforms, recording the maximum bearing capacity and deformation during the process.
2. Main application areas
Flexural and compressive testing machines play a key role in multiple industries:
| Industry | Specific applications |
|---|---|
| construction project | Test the compressive strength of concrete, bricks, and stone. |
| Manufacturing | Evaluate the mechanical properties of metal and plastic parts. |
| Scientific research institutions | Performance verification in new material development. |
| Quality inspection department | Ensure products comply with national standards (such as GB/T 17671). |
3. Popular technologies and industry trends in the past 10 days
Combined with the entire network search, recent attention in the field of flexural and compressive testing machines has focused on the following aspects:
