Purpose

Objective appraisal of pressure comfort is the key point of optimal designing of clothing. The purpose of this paper is to study a new method to provide pressure comfort for the waist of elastic pantyhose through the relationship between pressure and displacement using the finite element method (FEM).

Design/methodology/approach

This paper presented a simulation model of the waist cross section consisting of three parts, namely skin, soft tissue and lumbar vertebrae, respectively, according to CT scan. The finite element the model of waist cross-section was established using Mimics software. The pressure–displacement quadratic equation can be obtained using ANSYS software and fitting curves. Meanwhile, we divide the waist cross-section into 12 equal regions according to angle, and then the area shrinkage mass of the waist cross-section can be calculated, respectively.

Findings

In this research work, we got the displacement distribution trend of elastic pantyhose at the waist cross section according to the area shrinkage mass of 12 regions, and this displacement could be used as an objective evaluation index for pressure comfort. All these solutions supply a theoretical reference for optimal design of the women's elastic pantyhose.

Originality/value

The paper analyzed the relationship between pressure and displacement for the waist of elastic pantyhose using FEM, and then got the displacement distribution trend of elastic pantyhose at the waist cross section according to the area shrinkage mass of different regions. It can supply a new method to appraise pressure comfort.

弹性连裤袜腰部压力与位移关系的有限元模拟

目的

压力舒适性的客观评估是服装最佳设计的关键。本文的目的是研究一种使用有限元方法通过压力与位移之间的关系为弹性连裤袜的腰部提供压力舒适感的新方法。

设计/方法/方法

通过CT扫描，提出了腰部横断面的模拟模型，该横断面分别由皮肤，软组织和腰椎三部分组成。使用Mimics软件建立了腰部横截面模型的有限元。压力-位移二次方程可使用ANSYS软件和拟合曲线获得。同时，根据角度将腰部横截面分为12个相等的区域，然后可以分别计算出腰部横截面的面积收缩质量。

发现

在这项研究中，我们根据12个区域的面积收缩量，得出了弹性裤袜在腰部横截面的位移分布趋势，该位移可作为压力舒适性的客观评价指标。所有这些解决方案为女性弹性连裤袜的最佳设计提供了理论参考。

创意/价值

运用有限元方法分析了弹性连裤袜腰部压力与位移之间的关系，并根据不同区域的面积收缩量，得出了弹性连裤袜在腰部横截面的位移分布趋势。它可以提供一种评估压力舒适度的新方法。
