摘要：

为研究手臂活动角度对衣下间隙局部分布及服装局部散热性能的影响,利用三维扫描仪量化了出汗暖体假人在6种手臂姿势下,12个体段的衣下间隙体积及接触面积,提取了表征人体活动空间大小的物理指标,测量了服装各体段的局部热阻。结果表明:手臂的前伸角度与衣下间隙体积呈负相关性,而与接触面积呈显著正相关性,人体的活动空间随着手臂前伸角度的增加而显著减少;各体段的局部有效热阻呈现出非均匀的分布状态,局部衣下空气层体积越大、接触面积越小的体段,其有效热阻越大。服装的有效热阻可用衣下间隙体积与接触面积百分比共同预测。

关键词: 手臂活动角度, 衣下间隙, 服装舒适性, 接触面积, 服装热阻

Abstract:

To investigate the influence of arm angular motion on local air gap distribution and clothing heat transfer performance, a 3-D scanner was utilized to quantify the local air gap volume and contacting area of 12 body segments of a sweating manikin under six arm postures. An index to describe the activity space of human body was established and the clothing local thermal insulation was measured as well. The results show that the protraction angles of arm are significantly positively correlated with contacting area, but negatively correlated with air gap volume. The activity space of human body is dramatically decreased with the increase of arm protraction angle. The local thermal insulation of body segments displays an uneven distribution state, which body segments with bigger air gap volumes and smaller contacting areas show greater effective thermal insulation. The effective thermal insulation of clothing could be predicted by air gap volume and contacting area proportion.

Key words: arm activity angle, air gap volume, clothing comfort, contacting area, clothing thermal insulation
