科技冬奥智能穿戴式冰雪运动装备运动风险实验研究平台

Sports risk experimental research platform of intelligent wearable ice and snow sports equipment for High-Tech Winter Olympics

针对冰雪运动员训练时各体段及主要关节容易受伤的隐患,设计了智能穿戴式冰雪运动装备运动风险实验研究平台。平台以“基础研究—技术与装备研发—应用示范”全链条一体化实施为前提,建立冰雪运动员的运动学和动力学模型,通过研究适合各冰雪运动假人的力传感器、六轴IMU布置方案、基于惯性运动单元的坐标转换与姿态解算算法、卡尔曼滤波算法等,实现高速多模态数据采集。可为我国冬季项目竞技体育与大众体育的运动装备评价提供科技储备与平台支撑,同时为力学、制导控制相关专业的本科生及研究生培养提供了良好的实验条件。

Aiming at the hidden danger that each body segment and main joints are easy to be injured during training of ice and snow athletes,a sports risk experimental research platform of intelligent wearable ice and snow sports equipment is designed.Based on the premise of the integrated implementation of the whole chain of“Basic research-technology and equipment research-application demonstration”,the platform establishes the kinematic and dynamic models of ice and snow athletes,and studies the force sensor and six-axis IMU layout scheme suitable for each ice and snow sports dummies,the coordinate transformation and attitude solution algorithm based on inertial motion unit(IMU),Kalman filter algorithm and so on,the high speed multi-modal data acquisition is realized.It can provide scientific and technological reserves and platform support for the sports equipment evaluation of competitive sports and mass sports in winter,and provide good experimental conditions for the cultivation of undergraduates and postgraduates majoring in mechanics and guidance control.
