服装动态热阻测定及预测模型的研究进展

摘要

为探究风和人体运动对服装动态热阻的影响,基于对人体和环境间热对流的分析,结合实际研究数据,阐明风和人体运动对服装动态热阻存在显著影响.总结了风和人体运动作用下动态热阻的测试方法.动态热阻变化规律的定性分析表明,动态热阻值在风和人体运动作用下呈现下降趋势,且二者对动态热阻的影响程度随着风速和步行速度的增加逐渐下降.分类对正常工作服、冬季防寒服和轻质服装动态热阻具体数值的预测模型进行了概括和总结.研究认为,服装动态热阻预测模型未来的研究重点是动态热阻修正公式的优化和局部动态热阻变化规律2个方向.%To explore the influence of wind and body movement on clothing insulation,firstly,thermal convection between human body and environment was pointed out and the fact that wind and body movement have significant influence on clothing insulation was clarified based on theory analysis and existing research data.Then,the test methods of dynamic thermal is sulation,including human test and thermal manikin test,were summarized.Qualitative analysis of resultant insulation indicates that the thermal is sulation of clothing tends to decline under wind and body movement.Also,the influence of wind and body movement on thermal is sulation is weakened gradually with the increase of wind and body movement.Lastly,prediction models of dynamic insulation values were summarized according to different types of clothing.Future research on prediction model for clothing dynamic insulation will make breakthrough in optimizing the correction models and local dynamic insulation.
