    摘要:

    为了解在高原公路行车过程中驾驶员体力负荷与高原公路纵断面线形的关系,选取帕米尔高原国道G314路段进行高原公路实地行车试验。采用积分肌电值IEMG与中位频率MF的比值K作为评价驾驶员体力负荷的指标,通过对比经过170个变坡点附近被测驾驶员的体力负荷K的变化特征。定量分析K值随高程H、竖曲线半径R以及绝对坡差|ω|的变化规律,并建立关系模型。研究表明:高程、竖曲线半径和绝对坡差对驾驶员体力负荷均有明显影响;且在竖曲线半径和高程的共同作用下,高原公路驾驶员肌电负荷的变化更加明显。

    Abstract:

    In order to understand the relationship between the driver"s physical load and the profile of the high-altitude highway during the driving of the plateau highway, the G314 section of the national highway of Pamir Plateau was selected to conduct the field test of the plateau highway. The ratio K of the integral electromyography IEMG to the median frequency MF is used as an index to evaluate the driver"s physical load. By comparing the changes of the physical load K of the tested driver near 170 slope points. Quantitative analysis of the variation of K value with elevation H, vertical curve radius R and absolute slope difference |ω|, and establish a relational model. The research shows that the elevation, vertical curve radius and absolute slope have significant influence on the driver"s physical load; and under the combined action of the vertical curve radius and elevation, the change of the myoelectric load of the plateau driver is more obvious.
