Electronic universal testing machine After continuous research and development and improvement, it has gradually become the most widely used testing equipment developed in the materials industry. i.e. the electronic universal testing machine ?
With regard to the functions, electronic universal testing machines are usually divided into tension and compression. Bending, tearing, bursting, peeling and many other functions, but there are many differences in the actual test materials.
1. Take the tensile testing function of the electronic universal testing machine as an example
The most common universal electronic testing machine is tensile testing, mainly for metal materials, plastic materials, Polymer materials, composite materials and other materials Also, the corresponding test parameters are different for different tensile tests, and it is necessary to select the appropriate test mode, such as metal material testing, plastic material testing, etc.
According to customers' actual needs, there are also fracture strength test, elongation at break test, elongation at constant load, load at constant elongation , creep at constant Ttemperature and load etc. These complex train functions require powerful control software to implement.
2. Take the compression test function of the universal electronic testing machine as an example
Another common use of electronic universal testing machine is compression testing, mainly for plastic materials, polymer materials, composite materials, cartons, etc. Materials compression testing requires special compression devices.
The box compression test is based on the destruction of the box as the end condition ;The compression test vof plastic materials includes measurement of compression deformation under constant load, or measurement of stress under constant compression deformation, etc., which also requires relatively powerful control software to operate.
3. Take the bending test function of the universal electronic testing machine as an example
When using electronic universal testing machines, bending tests are also relatively common. The bending test is generally used to test panels, including metal panel, metal bar, plastic panel, wood-based panel, insulation panel, etc. material. A special three-point bending device is required.
Metal materials and plastic materials generally have good plasticity, so These 2 materials are generally subjected to three-point bending test. Materials such as engineered wood board and insulation board have poor plasticity, are hard and brittle, and are generally flex tested to test how much force they can withstand without breaking or causing other damage.
Fourth, take the electronic universal testing machine tear test function as an example
The electronic universal testing machine can be used for tear testing of clothing fabrics, non-woven fabrics, KuPlastic films and other materials are used, and the appropriate tear test can be selected to conduct the test, the test method is basically the same as the tensile test, but there are differences in the test parameter settings.
5. Take the burst test function of the universal electronic testing machine as an example
The electronic universal testing machine can be used for samples such as apparel fabrics, non-woven fabrics, plastic films, geotextiles, geomembranes, and geotechnical composites The bursting strength test requires a special bursting device, which is mainly used to test how much force these materials need to press wearing, simulating theunknown damage that can be caused to clothing, plastic films, geotextiles and their products for various reasons in everyday life.
Sixth, we take the peel test function of the universal electronic testing machine as an example
