The dynamic pressure is the critical factor for research on pressure comfort and optimal design of apparel products. This paper is devoted to study the top part of men's socks and divides the dynamic pressure on it into two parts: the pressure varying with time, and the pressure varying with walking of the wearer. A period of 12 hours is set for evaluation of the pressure varying with time, and the pressure at the top of socks of the wearer is measured at different intervals and simulated analysis of the measured pressure was carried out by using FEN software. Thus, the tendency of pressure and displacement change with time at top part of man's socks can be obtained. The walking process is divided into four phases, and the rules of pressure and displacement change with movement are analyzed. Meanwhile, lower leg cross section is divided into four equal regions according to angle, the correlation of contraction area in each region and the dynamic pressure at the top of socks of the wearer while walking is figured out. This study gives a theoretical reference for optimal design of the top part of men's socks.%动态服装压是研究服装压力舒适性以及服装优化设计的关键.以男短袜袜口为研究对象,将动态压力分为2个部分,分别为随时间变化的压力以及人体在行走过程中的压力.其中随时间变化的压力设定了12 h的时长,通过测量不同时间段穿着短袜后的袜口压力,运用有限元软件进行模拟分析,探讨了袜口处压力及位移随时间的变化趋势.将人体的行走过程划分为4个阶段,分别探讨了4个阶段压力及位移的变化规律,同时按照角度将腿截面等分为4个区域,并分别计算出各区域在动态过程中受袜口压力后面积缩量的分配关系,这些结论为袜口的优化设计提供了理论参考.
