摘　　要：为了提高车辆驾乘人员的热舒适性,探究了冬季气候条件下相对湿度对车舱乘员热舒适性的影响。采用FIALA人体模型结合客观热舒适性评价方法,通过对人体寒颤量、血管收缩量以及局部皮肤温度在不同相对湿度下的变化情况,分析了不同工况下乘员的热舒适响应特性及人体的热感觉状态。结果表明,相对湿度的变化影响人体自身的热调节作用,在最适相对湿度区间内人体会更加舒适,并且皮肤温差浮动更小,适应性也更强。基于相对湿度对乘员热舒适性的研究不仅可以为车舱热环境的改善提供重要帮助,而且可以为汽车智能座舱方面的研究提供参考。In order to enhance the thermal comfort of vehicle occupants,the influence of relative humidity on the thermal comfort of cabin occupants under certain winter climate conditions was investigated.The FIALA human model combined with the objective thermal comfort evaluation method was applied to analyze the thermal comfort response characteristics of passengers and the thermal sensation state of the human body under different working conditions.The changes of human shivering amount,blood vessel constriction amount and local skin temperature under different relative humidity were analyzed.The results show that the change of relative humidity affects the thermal regulation function of the human body.Within the optimal range of relative humidity,the human body will be more comfortable,with smaller fluctuations in skin temperature and stronger adaptability.Meanwhile,the research on occupant thermal comfort based on relative humidity can not only provide important help for the improvement of cabin thermal environment,but also provide some references for the research of automobile intelligent cockpit.
