摘要
根据二维平衡板上被测环节的移动与人体总重心的变化之间的联动关系,测得3个人体总重心点可以确定1个人体总重心圆。二维平衡板测量人体重心点的误差可造成人体总重心圆的严重失真。可以通过增加被测环节的移动幅度和对被测环节进行配重以增加人体总重心圆的圆心角和半径来减少失真。利用《人体总重心圆失真分析软件》通过调整总重心圆半径和圆心角的大小来控制人体总重心圆的失真程度,可根据计算结果来选择实验方案。
Based on the linkage relation of measured segment and gravity center,the study obtained one circle of gravity center by measuring three locations of general gravity center.The error of measuring the location of general gravity center would result in the serious distortion of the general gravity center circle.It was settled by increasing the extent of moving segments and adding extra weight to increase central angle and the radius of the circle.Applying the software of analyzing distortion of circle of general gravity center,we might select the experimental project by adjusting the radius and central angle to control the distortion.
