Due to the continuous deformations and irregularities of the surface of snow, alpine skis exhibit dynamic excitation, leading to drastic vibrations and decreased manoeuvrability. Therefore, attenuating these unwanted vibrations, while ensuring that the ski experience is not compromised, is an important challenge. The possibility of using granular material in a damping device is studied in this paper. A container that was partially filled with loose granules was fixed at the tip of an alpine ski to suppress vibrations by dissipating energy through collisions. The performance was verified experimentally by studying the transient response of a ski mounted in a horizontal cantilever orientation. Moreover, on-snow tests were performed. Different numbers of plastic granules were used as a dissipating material. To identify the nonlinear damping characteristics of the system, a Hilbert transform was used. In the laboratory test, the displacement amplitude decay was up to 16 percentage points higher when a granular dissipator was attached to the ski than without the damper. During field testing, acceleration amplitudes were 9% lower compared to the ski without the dissipator. This solution could possibly be adapted to other boardsports on a wide variety of terrain, including ground, water and snow.

由于雪表面的连续变形和不规则性，高山滑雪板表现出动态激励，导致剧烈振动并降低了机动性。因此，在确保不损害滑雪体验的同时，衰减这些不必要的振动是一项重要的挑战。本文研究了在减振装置中使用粒状材料的可能性。将部分填充有散装颗粒的容器固定在高山滑雪板的顶端，以通过碰撞耗散能量来抑制振动。通过研究水平悬臂方向安装的滑雪板的瞬态响应，通过实验验证了该性能。此外，进行了雪上测试。使用不同数量的塑料颗粒作为耗散材料。为了识别系统的非线性阻尼特性，使用了希尔伯特变换。在实验室测试中，将颗粒状耗散器安装在雪橇上时，位移幅度衰减比没有阻尼器时高出16个百分点。在野外测试期间，与没有消音器的滑雪板相比，加速度幅度降低了9％。该解决方案可能适用于包括地面，水和雪在内的各种地形上的其他木板运动。
