Problems solved by technology
On the one hand, in the prior art, the floor surface friction coefficient test method usually mainly tests the dynamic friction coefficient, and the test results cannot completely reflect the interaction between the athlete and the sports floor during the exercise process, and the detection method is difficult to reflect the actual movement of the athlete Effect
It has caused certain obstacles to the improvement and evaluation of professional sports floor surface performance, which is not conducive to the application and popularization of standardization of wooden sports floor surface performance testing.

Abstract
The invention discloses a rotary surface friction coefficient testing system. The system comprises a horizontal platform, an adjustable baffle, fixing baffles and a rotary loading device, wherein the horizontal platform is used for fixing a to-be-tested floor; the rotary loading device comprises a motor, a disc and a standard weight which are arranged from top to bottom sequentially, and a sensor is arranged in the disc; the motor is connected with the top of the sensor through a motor rotating shaft, and the bottom of the sensor is connected with the standard weight through a connecting component; elastic elements are connected between the sensor and the disc and do not deform in the initial state. The invention also discloses a testing method of the rotary surface friction coefficient testing system. The testing system is simple in structure, small in size and easy to operate; the test process is closer to the actual state, and test results are more accurate and more referential and scientific.
Description
technical field [0001] The invention belongs to the technical field of sports floor surface performance detection, and in particular relates to a rotating surface friction coefficient testing system and testing method. Background technique [0002] The sliding characteristics of the sports floor require the friction coefficient of the floor surface to be moderate. If the friction force is too large, the athlete will easily fall when he stops suddenly during the exercise, and the floor will increase the load on the athlete's leg muscles and ligaments, causing the athlete to move too quickly. Fatigue or injury; on the contrary, if the friction force is too small, the athlete will easily slip out when suddenly stopping during exercise, which will affect the performance of the athlete's technical level. Therefore, it is particularly important to test the surface performance of the sports floor, especially the research on the coefficient of friction. [0003] The relative movemen...
