实车环境下汽车座椅附加热阻研究
Research on additional thermal resistance of automotiveseats in real vehicle environment
摘要：
针对汽车座椅在用途和使用感受方面的特点,本文利用暖体假人,在实车环境中测试了3种类型的汽车座椅附加热阻,并分析了汽车座椅热阻的影响因素。研究结果表明:不同类型汽车座椅的附加热阻平均值从大到小依次为织布座椅(0.41 clo)、织布加仿皮组合式座椅(0.35 clo)、仿皮座椅(0.31 clo);服装热阻大的工况下,座椅能够提供更大的附加热阻;座椅角度越大,座椅整体附加热阻越大。本研究结论可为车舱内热环境进一步研究提供基础参数。
Abstract：
Based on the characteristics of automotive seats in terms of purpose and user experience, this paper uses a thermal manikin to test three types of additional thermal resistance of automotive seats in the real vehicle environment, and analyses the influencing factors of the thermal resistance of automotive seats. The results show that the average additional thermal resistance values of different types of automotive seats in order from large to small are fabric seats (0.41 clo), fabric and faux leather combination seats (0.35 clo), and faux leather seats (0.31 clo). Under the condition of high thermal resistance of clothing, the seat can provide greater additional thermal resistance. The larger the seat angle, the greater the overall additional thermal resistance of the seat. The conclusions provide basic parameters for further studies on the thermal environment in vehicle cabins.
