地铁乘员不同站姿方式的舒适性研究

Evaluation of passenger comfort in different standing postures in metro

随着城市地铁拥挤程度的增加,乘员站立的舒适性问题越来越受到重视。文章采用模拟仿真和现场试验相结合的方法,对地铁乘员不同站姿方式的舒适性进行研究。首先采用Sperling指标评价车辆运行品质,然后在乘员身体同一位置监测振动加速度,最后借鉴EN 12299标准评价研究不同站姿的舒适性。结果表明:不同速度下,地铁乘员不同站姿方式的舒适性有所差异,其中抓握吊环的舒适性优于其他站姿方式,空站舒适性最差,其他站姿方式相差不大。所以在充分考虑地铁内部空间合理布置安全的情况下,可以放置更多吊环,以提升人流高峰时地铁乘员在站姿方式下的舒适性。

With increasing congestion in metros, increased attention is given to the comfort of standing passengers. In this paper, the comfort of metro passengers in different standing postures were studied by combining simulations and field tests.Firstly, the Sperling index was used to evaluate the operating quality of the vehicle, and then the vibrating acceleration was monitored at the position the passenger’s body would be at.Finally, the comfort of different standing postures was evaluated by the EN12299 norm. The results showed that the comfort of metro passengers in different standing postures are different at different speeds. Passenger comfort when grasping round handles are better than standing passengers in other standing postures, whilst the comfort of simply standing being the worst, with little difference in comfort across the remaining standing postures. Therefore, in full consideration of the safety of a reasonable layout of the internal space in metro, more round handles can be placed to improve the comfort of metro passengers who are standing when travelling during peak hours.
