Some general knowledge in the use of electronic universal testing machine

The basic functions of an electronic universal testing machine are tensile performance, tensile strength and deformation rate, pull-off force, tear resistance, heat seal strength performance, roller peel test, 90-degree peel, rope pull-off force, trouser tear force, 180-degree peel, compression test, bending test, shear test, top break test, etc. to complete different tests, according to the different needs of customers, you can install different fixtures, wide specimen fixture Japanese type jig, British type jig, etc. comply with the standards of many countries. So, do you know about the universal testing machine?

Do you know some general knowledge about universal testers? Let me introduce it to you!

Here is the content list:

l Can all the functions of the electronic universal tester be used in the test?

l Is deformation the same as displacement?

Will the cell phone interfere with the electronic universal tester equipment?

This question should be divided into two parts to say, for the electronic universal test machine with the computer, if the cell phone notes close to the computer chassis, may produce some interference with the sound, which is similar to the usual own home Internet, cell phones produce the same interference, the impact is not significant. And for the test machine itself does not produce any impact, because the test machine transmission lines and so on are shielded lines, with a certain degree of anti-interference.

Can all the functions of the electronic universal tester be used in the test?

The answer is no. I have consulted many users, according to their response, if the function of the use rate of 70% is already very good, most users are generally the equivalent of only 50% use. In terms of test curves, electronic general test machine curves can simultaneously record force-deformation, deformation-time, force-time, stress-strain and force-displacement, and other test curves. However, most electronic universal testing machines focus more on the force-deformation curve, and even that curve is just observing the basic shape of the curve and that's it. So what is the reason for this phenomenon? The main problem is the manufacturer's design, testing machines in the design of the time can not be said to be individually suitable for which industry or which enterprise. And to meet the needs of the growing development, many features are designed to increase the scalability of new technologies to expand and add, more users from all walks of life. So more just in case, usually is not used.

Is deformation the same as displacement?

Before answering these two questions, let's understand the concept of this. Deformation refers to the process of testing the specimen, the specimen in the state of force generated force, and its shape and size also changed the phenomenon known as deformation, that is, the deformation of the specimen. Displacement is commonly known as the distance that the beam moves from the beginning of the force in the electronic universal testing machine (refers to the distance that the beam moves). In the less demanding tests, displacement can be used instead of deformation. However, the displacement of the beam is not the actual exact deformation of the test piece, and there is a certain difference between the data measured by the displacement and the data measured by the deformation. And there must be a relationship between deformation and displacement that is less than or equal to each other. If you want to measure more accurate deformation you must refer to the extensometer.

Through the above introduction, do you know a little more about the electronic universal testing machine? I hope this small introduction can help you!
