In UseMicrocomputer Controlled Universal Electronic Testing MachineBefore testing the mechanical properties of materials, one must become familiar with the relevant testing standards of the tested materials and have a clear understanding of the purpose of testing Material properties and the preparation process of the tested materials have samples and the whole testing process, and work strictly according to the following Electronic universal testing machine operating procedures:
The first step, sample preparation: Familiarize yourself with deFamiliarize yourself with the relevant test standards of the material to be tested, prepare samples according to the requirements of the standard and make good preparations for the prepared dimensions and other data labels.
Second step, start the test machine: First turn on the software measurement and control system on the computer, then turn on the power of the test machine, and then click Online button on the software to connect the computer and testing machine and select the appropriate testing type, such as e.g. tensile, tearing, bursting, etc.
The third step, test run: choose the appropriate speed to theRun test machine up and down, and make sure each system is running normally.
Step 4, Create new test records: According to the number of tests to be performed, create a new corresponding number of test records and fill in the corresponding lot number, serial number, test environment, sample size and other relevant data.
Step 5, Install the sample: Adjust the position of the moving beam of the universal electronic testing machine and place the sample on the holder. If a connected measuring device such as e.g. B. There is an extensometer, please install it.
Step 6. Selection of range: Select the appropriate test force and deformation range according to the test force and deformation range required for the test.
Seventh step, delete: delete test force, deformation and displacement.
Step 8, test speed: According to the test standard of the material to be tested, set the standard test speed; if there is no speed requirement in the relevant standard, it can be reduced to a reasonable speedit can be adjusted, and the speed should not be too high, so as not to affect the test accuracy.
Ninth stage, end condition: According to the test standard of the material to be tested, if the specimen is to be destroyed (e.g. tensile, compressive), select Fracture type assessment; If it is specified that the loading force on tensile or pressure ends when it reaches a certain value, select Target and Test Force; Deformation.
Step 10. Test Start: Click the Test Start button to start the test.
The eleventh step, the end of the test: After the test end condition is met, the computer decides and automatically presses the Test end button If you need to end the test halfway, you can also manually press the End of Test button on the software interface to end the test.
Step 12, Analysis of test results: Click click the Analyze button to display the corresponding test results.If you need to continue the test, you can click the Test button to return to the testIn the test operation interface, click the Next button to go to the next test record switch, and repeat the entire steps from the fifth to the eleventh step until the Test of all samples is complete.
The thirteenth step, output report: After the experiment is finished, you can click the Create Report button on the user interface to generate the test results in a Word document. If you need to print a paper report, you can use the printer directly as a reference. If the test data needs to be saved, click the Save button to save the test data to the database for future reference.
Step 14. Shutdown of the test machine: First turn off the power supply of the test machine, and then turn off the software-measurement and control system and the computer.
