摘　　要：为更好地发挥运动压力袜的作用,实现精准施压,使用三维人体扫描仪对人体小腿形态进行扫描,截取脚踝、跟腱与小腿肌转换处、小腿周长最大处以及胫骨初隆处截面曲线;同时运用有限元软件ABAQUS分别建立此4处截面模型,按照标准值施压,模拟穿着运动压力袜小腿截面的受压状态;分析腿部各截面压力与位移的关系;最后利用运动压力袜编织尺寸的预测模型,设计编织实验样品,进行压力测试分析。结果表明:穿着运动压力袜时,左、右小腿各截面受压状态具有较大差异,但各截面所受压力与产生的位移均呈现一次函数关系;运动压力袜编织尺寸与其压力以及人体腿部截面周长之间,符合二元一次方程关系式;实验样品的压力测试值与标准值的误差均低于5%,证明了此预测模型的有效性。In order to improve the functionality of sports pressure socks to achieve accurate pressure,a 3-D human body scanner was used to scan the shape of human legs,and the cross-section curves of the ankle,the transition between Achilles tendon and calf muscle,the maximum circumference of the leg and the tibial protuberance were measured.In parallel,finite element software ABAQUS was used to establish the four-section models respectively.According to the standard pressure value,the compression state of the leg section with sports pressure sock was simulated,and the relationship between the pressure and the displacement of each section of the leg was analyzed.Using the size prediction model of the knitted sport pressure socks,the sock test sample was designed,and the pressure test results were measured and compared with the standard pressure.The results show that when wearing sports pressure socks,the compression state of each section of the left and right leg varies greatly,and the pressure on each cross section is related to the displacement.The relationship between the size of the sport pressure socks and its pressure and the circumference of the leg section is linear.The error between the pressure test value and the standard value of the experimental sample is less than 5%,which proves the validity of the prediction model.
