Effect of flexural stiffness distribution of a ski on the ski–snow contact pressure in a carved turn

The design of the flexural stiffness distribution a ski is one important factors in its development. On other hand, ski–snow contact pressure during turn thought to be an factor skier’s feeling. However, relationship between and has not been made clear. purpose this study was understand how affects contacting pressure, applying load, condition through measurement on these items. system consisted deflection sensor beam with bending sensors, sensors installed near edge, four points load cells connected binding plate ski. Measurements were performed different distributions Skis A B hard snow soft surfaces. peak Ski boot center, stiffer under heel boot. An increase for caused less rear part ski, applied force from shifted forward. By fitting groove, so section after fitted sliding surface compression zone increased reduced B. whereas, it behind center. These results show that changes alter pressure.
