摘要

The inward displacement perpendicular to the body surface produced by external pressure is an important index to evaluate the pressure comfort and optimal design of apparel products. In this paper, we studied on the functional relationship of pressure, displacement and angle when the body was in dynamic state after dressing. The dynamic pressure was divided into two parts: pressure with time (instantaneous, 1, 2, 4, 8 and 12 h) and pressure with movement (walking which described as upright position, leg lift 10 degrees, leg lift 30 degrees and foot backward off the ground). The displacement of each point on the lower leg cross section in four stages of walking process and six periods of time were simulated by ANSYS finite element software. After fitting, the functional curves between pressure/displacement ratio and the angle were obtained. By comparing, we found out that all the curves were presented nearly complete uniform curving form no matter what state of the human body was in. That is, when the human body was under clothing pressure, the corresponding displacement value on the body surface can be calculated on the premise of the known pressure value at any point of lower leg cross section during the wearing process by functional equation. All these solutions supplied a theoretical reference for optimal design of the top part of men's socks.
