Electronic tensile machine is a kind of equipment used to test the mechanical properties of materials. It is mainly used to measure the deformation and fracture characteristics of materials under the action of tension, compression, bending and shear. It is widely used in materials research, quality control and production manufacturing. The following is a detailed introduction to the electronic tensile machine:
Components of electronic tensile machine
1. Main frame:
The main frame is the main structure of the whole equipment, usually made of high-strength steel or aluminum alloy to ensure the stability and durability of the equipment.
2. Drive system:
The drive system usually includes a servo motor and a ball screw to control the movement speed and position of the fixture.
3. Force sensor:
The force sensor is used to measure the force applied to the sample and convert the force signal into an electrical signal to output to the control system.
4. Displacement sensor:
The displacement sensor is used to measure the movement distance of the fixture to calculate the deformation of the sample.
5. Control system:
The control system includes a computer, a data acquisition card and a control software to control the test process, record data and perform data analysis.
6. Clamp:
The clamp is used to fix the sample to ensure that the sample does not slide or fall off during the test.
Main functions of electronic tensile machine
1. Tensile test:
Test the mechanical properties of materials under tensile force, such as tensile strength, elongation and elastic modulus.
2. Compression test:
Test the performance of materials under compression, such as compressive strength and compression deformation.
3. Bending test:
