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 invention discloses a simulation test device for surface friction resistance of a braided fabric and belongs to friction test devices which simulate real using friction in the operation state. A horizontal long hole and a longitudinal long hole in the surface of a rack platform are mutually perpendicular; a bearing plate is arranged on the upper surface of the horizontal long hole, and a standard brush is arranged on the upper surface of the longitudinal long hole; the standard brush produces a motion curve on the bearing plate; a rolling ball of an n-shaped frame presses the standard brush to produce friction to the bearing plate. Friction effects of all positions of a tested object are consistent; during friction, the friction force changes and 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...
