Study on dynamic pressure and displacement at top part of men′s socks using FEM

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.
