Problems solved by technology

[0002] The friction head of the current friction resistance testing device for the surface of the braided fabric is all in a fixed position for circular motion. The friction distance of the friction head is different at different radius positions, and the friction effect on the tested object is not uniform, which leads to a large error in the test conclusion. Big
When the current friction head makes circular motion, the pressure on the tested object is stable and constant, but when the tested object is rubbed in actual use, the pressure and friction always change, and the pressure and friction model used for testing is consistent with the actual The difference between the models is too large, which also leads to large errors in the test conclusions

Abstract

The friction testing device for the friction resistance of the braided fabric surface of the present invention belongs to the friction testing device with simulated actual use friction force in the working state. The horizontal long hole and the longitudinal long hole on the surface of the rack platform are perpendicular to each other; the horizontal long hole is provided with a loading plate, and the longitudinal long hole is provided with a standard brush; the standard brush generates a curved trajectory on the loading plate; The rolling ball of the "door" frame presses the standard brush to generate friction on the loading plate. Each position of the object to be tested is rubbed with the same effect; when rubbing, the friction force changes, and the friction force can be adjusted at any time.

Description

technical field [0001] The invention belongs to a friction testing device for the surface of braided fabrics, in particular to a friction testing device with simulated real use friction force in an operating state. Background technique [0002] The friction head of the current friction resistance testing device for the surface of the braided fabric is all in a fixed position for circular motion. The friction distance of the friction head is different at different radius positions, and the friction effect on the tested object is not uniform, which leads to a large error in the test conclusion. Big. When the current friction head moves in a circular motion, the pressure on the tested object is stable and constant, but when the tested object is rubbed in actual use, the pressure and friction always change, and the pressure and friction model used for testing is consistent with the actual The difference between the models is too large, which also leads to large errors in the te...
