在加速和侧步等网球特定运动中，鞋面组合提供的动态牵引力对运动员的受伤风险和表现起着重要作用。据报道，丙烯酸硬地网球表面增加了受伤的发生率，部分原因是鞋与表面界面处产生的牵引力增加。通常，用于测试和分类游戏表面的机械测试方法并不倾向于模拟在表面上参与期间发生的负载，因此不太可能预测人类对表面的反应。本文讨论的牵引力测试装置用于机械测量在与现实生活中玩耍相关的一系列正常负载条件下鞋和地面之间的动态牵引力。由于其沙子和丙烯酸漆混合面漆，丙烯酸硬地网球表面通常具有粗糙的表面形貌。表面微观粗糙度将影响粘弹性接触期间存在的摩擦机制，如鞋类与表面相互作用中所发现的那样。本文旨在进一步了解微观粗糙度和法向力对丙烯酸硬球场网球表面鞋面界面处产生的动态牵引力的影响。已经测量了一组受控的丙烯酸硬地网球表面的微观粗糙度和牵引力。讨论了微观粗糙度、法向力和牵引力之间的关系。
During tennis-specific movements, such as accelerating and side stepping, the dynamic traction provided by the shoe–surface combination plays an important role in the injury risk and performance of the player. Acrylic hard court tennis surfaces have been reported to have increased injury occurrence, partly caused by increased traction that developed at the shoe–surface interface. Often mechanical test methods used for the testing and categorisation of playing surfaces do not tend to simulate loads occurring during participation on the surface, and thus are unlikely to predict the human response to the surface. A traction testing device, discussed in this paper, has been used to mechanically measure the dynamic traction force between the shoe and the surface under a range of normal loading conditions that are relevant to real-life play. Acrylic hard court tennis surfaces generally have a rough surface topography, due to their sand and acrylic paint mixed top coating. Surface micro-roughness will influence the friction mechanisms present during viscoelastic contacts, as found in footwear–surface interactions. This paper aims to further understand the influence micro-roughness and normal force has on the dynamic traction that develops at the shoe–surface interface on acrylic hard court tennis surfaces. The micro-roughness and traction of a controlled set of acrylic hard court tennis surfaces have been measured. The relationships between micro-roughness, normal force, and traction force are discussed.
