Measuring device and method for snow friction coefficient

Abstract

The application relates to the technical field of snowfield friction coefficient measuring, in particular to a snowfield friction coefficient measuring device and a measuring method. The snowfield friction coefficient measuring device comprises a flywheel mechanism, a power starting mechanism and a supporting falling mechanism, wherein the flywheel mechanism comprises a flywheel, a supporting shaft, a bearing pedestal and a rotating speed sensor; the flywheel rotates with the supporting shaft as a rotating shaft; two ends of the supporting shaft are separately carried on the supporting fallingmechanism through the bearing pedestal; the rotating speed sensor is arranged at one end of the supporting shaft, and is used for detecting the rotating speed of the flywheel; the power starting mechanism is detachably connected with the supporting shaft, and is used for driving the flywheel to rotate; and the supporting falling mechanism can ascend or descend, and is used for driving the flywheel mechanism to be in contact with or separated from a snowfield. In a solving process of friction coefficients, linear acceleration is converted into rotational acceleration, and the snowfield friction coefficient measuring device is simple in structure, meets the portable requirement, and has the characteristic of accurate control, and can adapt to low temperature environment of a ski field, theoverall measuring process is stable, and the measuring is convenient and accurate.

Description

technical field [0001] The invention relates to the technical field of snow friction coefficient measurement, in particular to a snow friction coefficient measurement device and a measurement method for using the device to measure snow friction coefficient. Background technique [0002] In all snow sports, there is friction between the sports equipment and the snow surface. It is precisely because of the existence of friction that various types of ski equipment, suitable technical movements and targeted assistive technologies are derived. Due to the different venues and climatic conditions of snow sports, even the same sports venue has a great difference in the friction coefficient of the snow surface at each location. Taking alpine skiing as an example, there are differences in the altitude, snow density, air temperature, snow temperature and other indicators of the starting point area, the middle area and the end area, which directly lead to the change of the friction coe...
