Description of load deformation curve of tensile testing machine

Tension testerDifferent components play different test roles during the test. We have made corresponding analysis on the function and working principle of the tensile machine on our company's official website. The following is the full introduction of the drawing process of the "load----tension" curve of the tensile machine:

whenTension testerWhen the toothed rod is displaced horizontally, the drawing pen fixed with the toothed rod will move with the toothed rod. At the same time, the sample was elongated due to stress. The elongation of the sample causes a change in the distance between the upper and lower chucks, and its elongation is equal to the displacement of the lower chuck minus the displacement of the upper chuck. Since the displacement of the lower chuck is dragged by the wire master, the displacement of the lower chuck is the displacement of the wire master.

Tension testerWhen the wire master of the transmission system moves, it drives the pulley on the bent plate, so that the pulley group is driven accordingly, and drives the drawing barrel with the recording paper to rotate. In this way, the drawing pen draws a curve on the recording paper, which is called the "load---elongation" curve, or the "load----deformation" curve.
