Design of a new laboratory device for studying sliding on snow

A brief overview of experimental approaches to the study of the tribology of sliding of various bodies on snow or ice is presented, and a model and a digital twin of a tribological device is proposed. The deformation distribution of a tank with snow rotating at a target speed was obtained by modeling, and the work done by the friction force per sliding cycle was determined by testing the movement of a ski sample on a flat snow surface. The proposed device can be used to evaluate the efficiency of sliding on snow at a given temperature, snow structure, humidity, and the roughness of the ski surface sliding on snow.
