What requirements does the tensile testing machine have on the afterburner system?
No matter what kind of equipment has certain requirements during work or installation, the following editor will analyze the requirements of the tensile testing machine for the afterburner system with you, as follows: 1. Rigid testing machine frame of the testing machine The rigidity has been explained before, so I won’t repeat it here. 2. The tensile test space of the tensile testing machine requires different test spaces for the tensile test of different materials. Generally speaking, the tensile test space required for metal materials due to low ductility is not large, generally within 100mm; for non-metallic materials, especially The elongation of polymer materials is very high, and some are as high as 1000%. Therefore, the stretching space is relatively large, and the maximum stretching space is 1 meter. 3. The test fixture requires that at any position or during the test, the center line of the upper and lower chuck should be coaxial with the axis of the testing machine's afterburner, and its coaxiality: for the testing machine with a maximum capacity of not more than 5kN, it should not exceed 2mm/ 500mm; For testing machines with a maximum capacity greater than 5kN, the maximum allowable value of coaxiality is 15%; the chuck should be clamped reliably, not slipping, and can evenly clamp the sample; after the chuck removes the force or pulls off the sample, The jaws are not damaged; the jaws are interchangeable. 4. The horizontality of the moving beam of the tensile testing machine should be within 0.2/1000, and the movement should be stable within the working stroke, and there should be no side-to-side swing phenomenon. The speed of the moving beam and the allowable force shall meet the following requirements: For a testing machine with a maximum capacity not greater than 5kN, the maximum force of the testing machine should be applied at any speed; for a testing machine with a maximum capacity greater than 5kN: a. Moving If the speed is not more than 50mm/min, the maximum force value of the testing machine should be applied; www.laliceshiyi.comb. If the moving speed is greater than 50mm/min, the test force should not be less than 25% of the maximum force of the testing machine;
