摘　　要：针对传统列车舒适度研究在地铁列车舒适性长期服役监测方面的局限性,提出了一种基于移动终端的地铁列车舒适度评价方法。通过调研移动终端集成的传感器种类确定了地铁列车舒适度的影响因素为振动、噪声以及照度。结合问卷调查法和层次分析法确定各个因素对地铁列车舒适性影响的权重系数,综合现有标准和模拟实验建立影响因素的评价模型并制订了对应的评价标准,进而确定地铁列车舒适度评价方法,并将该评价方法集成到自主开发的移动终端的APP上,实现了列车舒适度数据的大范围采集。为了客观验证该方法的可行性,在地铁线路实验中采集专业测量仪器、移动终端和可穿戴设备的实验数据并进行分析。分析结果表明:列车平稳运行状态下,通过移动终端采集的振动、噪声和照度舒适度评价值的相对误差不超过5%、15%和18%;在两种工况下噪声舒适度评价值占总评价值的67.8%和76.5%,因此对列车舒适性影响程度最大的是噪声;基于提出方法的地铁列车舒适度评价结果与心率变异性频域指标(LF、HF和LF/HF)的分析结果趋于一致,客观地验证了该评价方法的可行性。移动终端驱动的地铁列车舒适度评价方法可为地铁列车舒适性大范围监测和长期服役性能演化分析提供新的方法和思路。Aiming at the limitations of traditional train comfort research in the long-term service monitoring of subway train comfort,this paper presents a comprehensive evaluation method of subway train comfort based on mobile terminals.By investigating the types of sensors integrated in mobile terminals,it is determined that the factors affecting the comfort of subway trains are vibration,noise and illuminance.Combined with questionnaire survey and analytic hierarchy process,the weight coefficients of each factor's influence on the comfort of subway trains are determined.The evaluation models and evaluation standards of each factor are established based on the existing standards and simulation experiments,and then the evaluation method of subway train comfort is determined.The proposed method is integrated into the self-developed mobile terminal APP to realize large-scale collection of train comfort data.In order to objectively verify the feasibility of this method,the experimental data from professional measuring instruments,mobile terminals and wearable devices are collected in the subway line experiment.The results of the analysis show that:when the train is running smoothly,the relative errors of the vibration,noise and illuminance comfort evaluation values collected by the mobile terminal shall not exceed 5%,15%and 18%respectively;the noise comfort evaluation value accounts for 67.8%and 76.5%of the total evaluation value under two working conditions,therefore the greatest influence on train comfort is noise;the evaluation results of subway train comfort based on the proposed method tend to be consistent with the analysis results of heart rate variability frequency domain indicators(LF,HF and LF/HF),which objectively verify the feasibility of the evaluation method.The mobile terminal-driven subway train comfort evaluation method can provide new ways and ideas for large-scale monitoring of subway train comfort and long-term service performance evolution analysis.
