一种客观判定高速列车综合舒适度的方法

提出了一种高速列车综合舒适度的客观评定方法,综合考虑了振动、噪声、压力、温度、湿度、照度6个影响因素。通过Delphi、AHP方法的专家问卷调查确定了上述影响因素的权重,并且利用模拟试验问卷调查给出了噪声、压力、温度、湿度、照度等几种舒适度影响因子建议判定标准的线性回归模型,从而得到了综合舒适度的计算方法。实车试验表明该方法有较好的评定效果,为今后列车综合舒适度的评定标准提供数据支撑和理论依据。

An Objective Method to Evaluate the Synthesis Comfort of High-speed Train

This paper present an objective method to evaluate the synthesis comfort of high-speed train.In our method,influencing factors such as vibration,noise,pressure,temperature,humidity and illuminance are taken into consideration.The single factor weight to the synthesis comfort is determined by Delphi and AHP expert questionnaires.The correlation between single factor and the comfort evaluation is established by linear regression models.The parameters of the linear regression model are obtained by simulation experiment and questionnaires survey.Thus the synthesis comfort can be calculated by experiment data.The effective performance of our method is demonstrated by full-scale train experiment,and the research can be seemed as data support and theoretical basis to establish the synthesis comfort assessment standard of high-speed train.
