SKI VIBRATIONS AND DAMPING

Skis and runners sliding on snow like to vibrate. Soft snows tend to dampen ski vibrations but icy surfaces often set up severe oscillations. A feedback situation, such as driving on a gravel road, may also exist since vibrating skis create washboard conditions. Skis are subject to a range of forcing functions from low frequencies in big moguls (bumps) to 200–300 Hz frequencies at high speeds on icy surfaces. Analysis is complicated by random inputs, nonprismatic and anisotropic structures, and varying suspension systems. Copyright © 1994, Wiley Blackwell. All rights reserved
