Haida instrument analyzes the gauge measurement method of rubber tensile testing machine for you

Haida instrument analyzes the gauge measurement method of rubber tensile testing machine for you. After purchasing Haida rubber tensile testing machine, you will learn the gauge measurement method of rubber tensile testing machine, which is applicable to all tensile machines. Here, Haida is here to explain in detail the gauge distance measurement method of rubber tensile testing machine

I. importance

1, which directly affects the accuracy of the test

2. There is a close relationship between the tensile value and the gauge distance 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, which is convenient to calculate the items required by the test

6. The measurement of the gauge distance of the sample is an important data for calculating the elongation of rubber

2. The measurement method

1. Manual measurement

1) set a ruler and two horizontal gauge rods that can move in the vertical direction vertically beside the moving rod of the gripper

2) during the tensile test, observe the change of the gauge distance on the sample with your eyes. 1. On the one hand

3) manually control two gauge rods, Make it synchronized with the gauge distance on the sample

4) and record the moving distance of the gauge rod on the ruler at the same time

disadvantages:

the error of manual measurement is very large

2. The sudden change of supply and demand pattern of automatic measurement has brought the market ldquo; in a short time; High fever rdquo

1) use the contact sensor to measure the change of the gauge distance in real time

2) there are two main installation positions of the sensor mobile device:

① install it on the gripper; Even the car interior is also 1 sample

② on the sample

disadvantages:

1) the dead weight of the gauge rod contacting the sample will pull the sample downward, affecting the tension measurement

2) the clamping of the gauge rod has a certain impact on the zero point tension of the clamped part, so that it cannot be stretched freely

Haida instrument analyzes the gauge distance measurement method of rubber tensile testing machine for you. Through the detailed introduction of Haida above, users can use the above two methods when using the tensile machine
