【摘要】：为了解高原公路线形对驾驶员肌电特性影响,寻求提高行车安全途径以及今后道路线形设计参考依据。通过在新疆帕米尔高原G314路段进行驾驶员行车试验,利用生物反馈仪提取受测驾驶员肌电信号,利用频域分析方法选取平均功率频率(MPF)作为测评指标,定量分析其在海拔与道路线形影响下的变化规律,同时建立关系模型。分析结果表明:驾驶员颈部MPF会随着海拔的升高而减小;平曲线半径逐渐减小的路段上,驾驶员颈部MPF会减小,而纵坡度变化对MPF的影响并不显著;线形组合值增大会导致驾驶员颈部MPF减小;海拔与线形组合值共同影响下,驾驶员颈部MPF变化明显,海拔越高、线形组合值越大,驾驶员颈部MPF越小。
[Abstract]:In order to understand the influence of plateau highway alignment on driver's electromyography (EMG) characteristics, this paper seeks to improve the safety of driving and the reference basis of road alignment design in the future.The driver driving test was carried out in G314 section of Pamir Plateau in Xinjiang, and the EMG signal was extracted by biofeedback instrument, and the average power frequency (MPF) was selected as the evaluation index by frequency domain analysis method.Quantitative analysis of its changes under the influence of elevation and road alignment, and the establishment of a relational model.The results show that the neck MPF of the driver will decrease with the increase of altitude, the MPF of the driver's neck will decrease in the section where the radius of the plane curve decreases gradually, but the change of the longitudinal slope will not have a significant effect on the MPF.The increase of linear combination value will lead to the decrease of neck MPF, and under the influence of altitude and linear combination value, the change of MPF in driver's neck is obvious. The higher the altitude, the bigger the linear combination value, the smaller the MPF of driver's neck.
