目的了解石太(石家庄-太原)客运专线动车乘务员和乘客舒适度及车厢内气压、噪声、风速.方法于2011年对石家庄客运段石太客运专线动车全体乘务员(244人次)和部分乘客(377人次)进行乘车舒适度问卷调查,对时速250、200 km/h车速下动车车厢进行气压、噪声和风速全程动态监测.结果与250 km/h车速时比较,200 km/h时乘务员严重不适的构成比降低,差异有统计学意义(Z=-5.024,P＜0.05)；与250 km/h车速时比较,200 km/h时乘务员短时间不适消除的构成比增高,差异有统计学意义(Z=-3.675,P＜0.05).250和200 km/h车速时乘务员因气压、噪声引起的耳部不适构成比的差异无统计学意义(P＞0.05).与250 krn/h车速比较,200 km/h时乘客严重不适的构成比降低,差异有统计学意义(Z=-8.403,P＜0.05)；与250 km/h车速比较,200 km/h时因气压、噪声引起的耳部轻度不适的构成比增高,耳鸣和耳膜不适的构成比降低,差异有统计学意义(Z=-2.243,P＜0.05),250和200 km/h车速时乘客不同不适消除时间的构成比差异无统计学意义(P＞0.05).动车进出隧道过程中噪声短时超标.结论该线路250 km/h车速时动车的乘车人员不适感强于200 km/h,可能与动车穿越隧道时风速和噪声的突变有关.

Objective To explore the crew and passengers' comfort on the Shijiazhuang-Taiyuan passenger dedicated line and physical factors,such as air pressure,noise,wind speed.Methods Comfort investigation of all the crew (n=244) and passengers (n=377) on the Shijiazhuang-Taiyuan passenger dedicated line at speed of 250 km/h and 200 km/h and the detection of the air pressure,noise and wind speed were performed in 2011.Results Significantly higher ratio of comfortable feeling,lower ratio of seriously discomfortable feeling were observed in crew and passengers at 200 km/h compared with those at 250 km/h (P＜0.05),as well as rapid disappearance of discomfortable feeling in crew (P＜0.05) and significantly higher ratio of lightly discomfortable feeling and lower ratios of tinnitus and eardrum discomfort induced by air pressure and noise in passengers at 200 km/h.No significant difference was observed in ear discomfort induced by air pressure and noise among crew,and the duration of disappearance of discomfortable feeling among passengers between 200 km/h and 250 km/h.The noise in carriages exceeded the related standard when the high-speed train passing through the tunnels.Conclusion The individuals feel more comfortable at 200 km/h than 250 km/h in this line.,which may be related with rapid variation of wind speed and noise when the train passes through the tunnels with high speed.
