DESIGNING A NEW EXPERIMENTAL SYSTEM FOR STUDYING SLIDING ON SNOW

In this paper, we present a brief review of experimental approaches to the study of the sliding tribology of various bodies on snow or ice and propose a model and a digital twin of a tribological system. The distribution of the deformation of a tank filled with snow rotating at a specific speed was obtained by numerical simulation, and the work done by the friction force per sliding cycle was determined by testing the motion of a ski sample on a flat snow surface. The proposed system can be used to evaluate the sliding performance on snow at given temperature, snow structure, humidity, and the roughness of the ski surface sliding on snow.
