What is a hydraulic tensile testing machine?
Hydraulic tensile testing machine is a device used to test the mechanical properties of materials. It is widely used in tensile, compression, bending and other mechanical property testing in metal, plastic, rubber, composite materials and other fields. It applies force through a hydraulic system and can accurately measure key parameters such as strength, elastic modulus, and elongation at break of the material. The following is a detailed introduction to the hydraulic tensile testing machine.
1. Working principle of hydraulic tensile testing machine
The hydraulic tensile testing machine presses hydraulic oil into the cylinder through a hydraulic pump, pushing the piston to generate tension or pressure, thereby applying load to the sample. Its core components include hydraulic systems, control systems, sensors and data acquisition systems. The following is its main workflow:
| steps | Description |
|---|---|
| 1 | Specimen clamping: Fix the specimen in the upper and lower clamps of the testing machine. |
| 2 | Hydraulic loading: The application of tension or pressure through a hydraulic system. |
| 3 | Data collection: The sensor records the force value and deformation in real time. |
| 4 | Data analysis: Software processes data and generates test reports. |
