The Performance Sports Engineering Laboratory has had a 10 year partnership supporting the British Skeleton team. We have been part of the team that helped win 5 medals, including 3 successive gold medals at the winter Olympics [Amy Williams(2010) and Lizzy Yarnold(2014, 2018)]. A series of EngD and PhD student's research has progressively allowed a greatly enhanced understanding of the fundamental science that allows the combination of athlete and sled to descend a track as rapidly as possible. There is still a significant question of how best to design the sled and its runner such that the athlete sliding can maximise their control of the sled trajectory. The dynamic interaction of the runner contact with the ice, design of the limited edges that bite into the ice, the distortion of the sled activated by the slider and their reaction time and training all play a part.The project will build on the expertise of the research team in achieving performance gains in elite sport (Turnock,Banks); understanding of how human-in-the-loop dynamic test environments (Taunton); advanced control engineering (Rogers); and ice physics (Symmonds) can be used to allow the development of a free-running human activated simulation of a track descent for the first time. Significant developments have already taken place and this project will concentrate on exploiting the understanding already gained but within the context of a virtual reality environment that captures the essential physics, human factors and a whole system model.

性能运动工程实验室已经有10年的合作伙伴关系，支持英国骷髅队。我们是帮助赢得5枚奖牌的团队的一部分，其中包括在冬季奥运会上连续三次获得金牌[艾米·威廉姆斯（2010年）和丽兹·亚诺德（2014年、2018年）]。一系列的工程博士和博士生的研究已经逐渐使我们大大提高了对基础科学的理解，使运动员和雪橇的组合能够尽可能快地下降。还有一个重要的问题是，如何最好地设计雪橇和它的跑步者，使运动员滑行可以最大限度地控制雪橇的轨迹。跑步者与冰面接触时的动态互动、咬入冰面的有限边缘的设计、滑块激活的雪橇的变形以及他们的反应时间和训练都起到了一定的作用。该项目将以研究团队的专业知识为基础，实现精英运动的成绩提高（托尔克，班克斯）；了解人在环动态测试环境（Taunton）；先进控制工程（罗杰斯）；和冰物理（Symmonds）可以用来开发一个自由运行的人类激活的轨道下降模拟，这是第一次。重大的发展已经发生，这个项目将集中在利用已经获得的理解，但在虚拟现实环境的背景下，捕捉基本的物理，人为因素和整个系统模型。
