Active vibration damping of the alpine ski

AbstractThe Purpose of this work was to present the damping of a ski with piezoelements and to animate a ski with help of energy respectively. The idea was to eliminate the disturbing and allow non–disturbing frequencies. This should be implemented with an active damping system that consists of pizoelements. The result of this project shows that with the help of piezoelements it is possible to react to vibrations engendered by the ski-slope. But if this damping system with its very high mode of action is to be used in the normal ski collection, it has to be made smaller and more efficient

MEASURING DYNAMIC SKI BEHAVIOR WITH STRAIN GAUGES

The performance of a ski is influenced not only by geometric properties such as length, width, camber height, side cut and thickness; but also by the deformation behaviour caused by the mechanical properties (Kaps et al. 2001). The purpose of this work was to evaluate the influence of flexural and torsional stiffness on the deformation of a ski during turns
