Since many years, the field of active control of vibrations has been growing up and many new applications using smart actuators have been developing. In 2003, CEDRAT TECHNOLOGIES in collaboration with SKI ROSSIGNOL initiated a project supported by ESA where these concepts (smart material and active control of vibration) were adapted and applied on a ski structure. The project aim was to damp the large modes of vibrations keeping the robustness of the control and the static loads during the ski ride.
