CTEC: active control of vibration applied on a ski structure

360°R&D, the ASRC Magazine, comes back on CTEC success story relative to active control of vibration applied on a ski structure.

The objective of the project was to damp the large modes of vibrations keeping the robustness of the control and the static loads during the ski ride. Vibrations  up to 80mm pk-to-pk were reduced with an attenuation up to 30dB and according to the ski tester comfort and performances were improved on different types of snow.

For your information CTEC has developped an Educational Kit (Active Control of Vibration) that received the first price in the University Challenge 2011 organized by Bruel & Kjaer for the project relative to “Study and control of the vibration behaviour of a ski”.
