| Summary: | through the years, speed skating has undergone several transformations, one of them has been the change in the size of the wheels and the variation of the technique used in competition, these changes aff ect the performance of athletes and it has generated changes in the forces applied to the frame skate. This has led to a lifetime reduction of the product, for this reason a study was done with a high performance athlete, a static and a dynamic study was performed about the loads over the skate frame. While the double-push technique is being executed by a professional skater roller, computational models were done for six types of current commercial frames, stress and fatigue safety factors were calculated, these values were used as a starting point for a geometric redesign which optimizes the stress distribution and increases the safety factor. It was possible to obtain a fi nal version of a light frame and an increase of 230 % on the fatigue safety factor. |
