中文摘要： 公共交通工具（如轨道列车、公共汽车等）内的噪声和振动水平与建筑环境有显著差异，研究交通工具内噪声及振动扰量复合作用对人体热舒适的影响机理，有助于将经典的建筑热舒适模型从建筑环境领域扩展到其他人工环境领域。本研究采用心理学、生理学、建筑环境学、人机工程学等交叉学科的基础理论与实验分析方法，在不同噪声和振动扰量及温湿度水平下开展人体热反应实验，分别研究噪声和振动扰量对表征热舒适的生理、心理指标的影响，进而研究噪声、振动和热环境参数复合作用对生理、心理指标影响的协同或拮抗作用，筛选反映噪声、振动和热环境参数复合影响的代表性生理指标；分析噪声和振动扰量对热舒适阈值产生的偏移，建立可反映噪声和振动扰量复合作用的热感觉评价模型及模糊神经网络热满意度预测模型。为交通工具环境中热环境参数的范围界定提供理论依据。

英文摘要： The environment in public transport such as railcars and buses is distinctly different from building environment in terms of noise and vibration. It will be helpful to extend the application of classical thermal comfort model from building environment to artificial environment by studying the influential mechanisms of noise and vibration and their combined effects on the passengers' thermal comfort. In this project, a series of experiments will be carried out in a climate chamber to test the thermal responses of subjects under scenarios with different air temperature, humidity, noise and vibration. The effects of noise and vibration on the passengers' physiological and psychological indices, relating to thermal comfort, are firstly investigated independently, and then their synergic and antagonistic effects on these indices will be analyzed. Typical physiological indices are chosen to indicate the combined influence of noise, vibration and thermal environmental parameters. Besides, the deviations of thermal comfort votes will be quantified, considering the effects of noise and vibration. A predicted model based on human thermal balance model and an evaluation model based on fuzzy neurosis network will be developed to investigate the thermal sensation and thermal satisfaction of the passengers under the environme
