【摘要】 为了研究袜口处极径以及曲率半径分布与压力的关系,通过三维人体扫描仪对30位年龄在20～22岁之间标准体型的男子踝骨以上6 cm处腿围形态进行扫描,确立袜口处腿部标准截面形态.在此基础上通过曲线拟合得到袜口标准截面形态方程,并通过极坐标变换的方式获取人体腿部标准截面曲线的极径以及曲率半径的极坐标方程,进而得到截面曲线的极径和曲率半径随角度变化的规律,为袜口处压力预测数学模型建立提供一定的参考.更多还原

【Abstract】 In order to study the relationship between pressure and distribution of sectional radius of curvature radius,3D body scanner was used to get the normal leg section forms at sock-tops 6cm above ankle for 30 men of normal size between 20～22 years old.On this basis,the equation of standard section of the tops was obtained by curve fitting and the polar coordinate equation of the polar radius and curvature radius of standard leg sectional curves acquired by polar coordinate transformation,by which the law of the pole radius and the curvature radius of the sectional curves changing with the angle was thus obtained.It makes a reference for mathematic model on sock-top pressure prediction.更多还原
