Advancements in Sledge Sports Research: Impact of Surface Treatment and Hardness Measurement

Scientists from the Institute of Mechanics and Mechanical Engineering of the Faculty of Mechanical Sciences, Transport and Aeronautics of RTU started research related to sledge sports more than ten years ago, trying to find out how the surface treatment of sleds affects sliding on ice. Since then, various studies have been carried out, for example, in the Latvian Science Council project “Carbon-enriched multifunctional nanostructured smart coatings (NVP) for high-tech applications and their production using the high-power magnetically compressed plasma method”, knowledge about microhardness measurements has been developed, including surfaces with nanocoatings. The experience and knowledge gained there have allowed the development of the new method of controlling the hardness of the slats.

The proposed methodology will make it possible to clearly determine whether unauthorized manipulations have been carried out with the inclinations, which cannot be detected with the current method. The institute’s leading researchers predict that it will bring the competition closer to the conditions where the skill of the athlete will have a greater impact on the result than illegal techniques of handling the slopes.

The International Bobsleigh and Skeleton Federation is familiar with the research and performance of scientists in more accurate characterization of the slope parameters and improvement of sliding properties.

Scientists also cooperate with the Latvian bobsled and skeleton teams in measuring the geometry and hardness of the sleds, helping the athletes to better prepare for competitions.

Measurements are made in the “Mitutoyo” laboratory at RTU. Laboratory equipment for measuring dimensions is provided by the company “Mitutoyo Poland Sp.oo”.
