概要 两维坐标上的撑竿跳高翻转动力学分析是用一个由九个环节组成的刚体模型完成的。用16毫米高速摄影机拍摄五个优秀撑竿跳选手的比赛动作,再把影片转换成数字数据并对其进行平滑处理,然后计算出每一名选手肩部、左髋、左膝、右髋、右膝以及竿子下握手相对于上握手所产生的合转矩函数曲线,最后比较选手之间的每一关节转矩曲钱并述及所观察到的动作技术。
Summary Two-dimensional coordinates of the pole vault flip dynamics analysis is a nine-part rigid body model. Shooting five excellent pole vault players with a 16mm high-speed camera, converting the video to digital data and smoothing it out, and then calculating each player’s shoulder, left hip, left knee, right hip, Right knee and pole under the hand shake handshake with the resultant torque curve, the final comparison between the players each torque between the torque Quercus and the observed action technology.
