摘　　要：现代竞技体育与科技的关系越来越密切,有关冰刀减阻与高效驱动的技术研究,对于提高滑冰运动员的竞技水平和比赛成绩有着重要意义。分析冰刀的受力情况和冰面摩擦学特性,认为摩擦生热机制作用下冰面水基润滑膜的构建是实现极低摩擦系数的关键。指出了滑冰运动的驱动力由运动员施加在冰刀上的蹬冰力提供,冰刀材料需具有良好的刚度、韧性和耐磨损性能以避免冰刀机械失效,从而获得有效蹬冰力。探讨采用真空物理镀膜工艺制备纳米金属陶瓷涂层对于实现冰刀减阻和高效驱动的有效性和可行性。Science and technology play more and more important role in modern competitive sports,and it is of great importance for the research on friction reduction and efficient driving to enhance performance in ice skating.The friction and driving force mechanism between ice and skate blade were studied to analyze the reason of low friction coefficient when skating,which was thought to result from a lubricating water film formed through frictional melting,while the driving force in skating was considered to be a result of griping force the blade had on the ice with a suitable bite angle.The application of PVD coating technology was also studied for friction drag reduction in the way of lower coefficient of thermal conductivity resulting in positive frictional melting,and high efficiency driving in the way of enhancement of mechanical performance such as stiffness,toughness and wear resistance to avoid mechanical failure.
