Development of a methodology to predict and control dynamic properties of backcountry skis

Genuine Guide Gear(G3)是一家独立拥有和运营的行业领先的齿轮制造商 野外滑雪和单板滑雪。18年来，G3一直致力于生产创新设备 并且最近在他们的生产线上引入了大量的碳纤维复合材料。对.的使用 碳可以节省重量并增加硬度，从而提高性能重量比。 然而，具有高刚度值的材料通常具有较低的阻尼能力，而碳基滑雪板 在更坚硬的雪地条件下，容易变得不那么宽容。松软的雪往往会抑制滑雪的振动，但表面结冰 而坚硬的积雪会引起严重的震荡，影响滑雪者的控制和平衡。 G3正在积极研究一种预测碳基滑雪板机械性能的方法，并 控制动态特性和提高高频下的减振性能的策略。滑雪举重是一种 重大问题，因此减震解决方案不能增加重量，并且必须具有成本可行性 制作。 Genuine Guide Gear在复合滑雪板设计方面拥有广泛的专业知识，但资源有限 发展其在碳增强复合材料减振方面的专业知识。该公司已要求 不列颠哥伦比亚大学复合材料研究网络(CRN)的协助，以提供 在这一领域的指导。

Genuine Guide Gear (G3) is an independently owned and operated manufacturer of industry-leading gear for backcountry skiing and snowboarding. For 18 years, G3 has been committed to produce innovative equipment and has recently introduced significant amounts of carbon fiber composite to their product lines. The use of carbon allows for weight savings and increased stiffness, thereby improving the performance-to-weight ratio. However, materials with high stiffness values generally have low damping ability, and carbon-based skis are prone to be less forgiving in firmer snow conditions. Soft snow tends to dampen ski vibrations but icy surfaces and hard snow induce severe oscillations that affect the skier's control and balance. G3 is actively researching a methodology to predict the mechanical properties of carbon-based skis and strategies to control dynamic properties and improve damping performance at high frequencies. Ski weight is a significant issue, therefore the damping solution must not increase weight and must be cost feasible to take to production. Genuine Guide Gear has extensive expertise in the design of composite skis but has limited resources to develop its expertise on damping in carbon-reinforced composite materials. The company has requested the assistance of the Composites Research Network (CRN), at the University of British Columbia, to offer guidance in this field.
