【摘要】 针对评价车内挥发性有机化合物（Volatile Organic Compounds,VOCs）对乘员舒适性影响的方法未能综合考虑车内VOCs的气味和对健康危害性的问题，将汽车内部作为一个室内微环境体系，基于车内VOCs的天然本底质量浓度、国标限值以及检知嗅阈值，采用韦伯-费希纳定律，建立了综合考虑VOCs气味与健康危害的乘员舒适性评价方法 .将变异系数法与三角模糊函数相结合，定量分析车内VOCs主要组分对乘员舒适性的影响权重以及乘员舒适性等级，提出一种基于评语集的定量分析来比较不同车型乘员舒适性的理论方法 .应用上述评价方法与理论进行案例研究，结果表明，4种车型中，第4种车型的乘员舒适性最佳.更多还原

【Abstract】 As the evaluation of passengers’ comfort is not comprehensively considering the effect of the odor of Volatile Organic Compounds(VOCs) or health hazard of VOCs in a car in the present work, automobiles were taken as a kind of indoor micro-environmental system. The Weber-Fechner law was applied to establish an evaluation method of passengers’ comfort by comprehensively considering both the odor and health hazard of VOCs in a car based on the natural background concentration of typical VOCs compositions, national standards, and the olfactory threshold data. It was also the first time to quantitatively determine the influence weights of the typical VOCs compositions on passengers’ comfort and passengers’ comfort levels combined with the coefficient of variation method and triangular fuzzy theory. In addition, this paper proposed a method of quantitatively comparing passengers’ comfort in different cars based on the comment set and carried out a case study using the above proposed evaluation method. The case study indicated that,among the four types of cars,the fourth car presented the highest passengers comfort level.更多还原
