Haida Instrument analyzes the gauge measurement method for rubber tensile testing machine
Haida instrument for you to analyze the rubber tensile tester gauge measurement method, after purchasing Haida rubber tensile testing machine, will learn rubber tensile testing machine gauge measurement method, suitable for the tensile machine. Here, Haida analyzes the gauge measurement method of the rubber tensile testing machine for us in detail.
1, directly affect the accuracy of the test.
2. There is a close connection between the tension value and the gauge length in the tensile specimen
3, after the test is completed, the accurate stress-strain curve can reproduce the test process
4, and clearly reflect the value of each test section
5, to facilitate the calculation of test requirements of the project.
6. The measurement of the gauge length of the sample is an important data for calculating the rubber elongation. 2. Measurement method
1, manual measurement
1) Vertically set one scale and two vertical scale rods that can be moved in the vertical direction near the gripper moving rod
2) Visually observe the change of gauge length on the specimen during the tensile test
3) Manually control two gauge rods to synchronize them with the gauge length on the specimen
4) Simultaneously record the movement distance of the gauge rod on the scale.
Disadvantages:
Manual measurement error is very large
2, automatic measurement.
1) Instant measurement of gauge changes with touch sensors
2) There are two main installation positions for the sensor mobile device:
1 installed in the holder;
2 on the sample.
Disadvantages:
1) The self-weight of the gauge rod that contacts the specimen will pull the specimen downward and affect the pull force measurement
2) The clamping of the gauge bar has a certain influence on the tension of the clamped part, making it unable to stretch freely.
Haida instrument for you to analyze the rubber tensile tester gauge measurement method, through the Shanghai Da Xiaobian detailed introduction, the user can use the above two methods when using the pull machine!
