基于人机工程学的山区公路桥头跳车分析评价

Analysis and Evaluation of Vehicle Bumping at Bridge-head of Mountain Highway Based on Ergonomics

桥头跳车是山区公路小桥涵运营中的一种常见现象,它影响了行车的舒适与安全。选取了人机工程学指标,包括汽车振动加速度和驾驶员心率,作为桥头跳车对行车安全影响的评价指标;通过行车实验和对比实验,从乘车舒适性和振动知觉两方面,并结合ISO2631全身振动的相关规定,对内蒙古S203线山区某路段桥头跳车的严重程度进行分析评价,并给出了改善建议。

Vehicle bumping at bridge-head is a kind of common phenomenon in the small bridges and culverts of mountain highway under operation. It directly affects traveling comfort and safety. This article chooses the indexes on ergonomics, including motor vibration acceleration and driver＇ s heart rate,as the evaluation indexes of the impact by the vehicle bumping at bridge-head to traveling comfort and human vibration sensitivity, through the driving experiment and comparing experiment, referring to the related regulations of whole body in ISO2631, and the degree of vehicle bumping at bridge-head of $203 road in the Inner Mongolia autonomous region has been analyzed and appraised, then some improving suggestion has been provided.
