摘要

长期以来,人们一直通过主观调查或对身体加速度的客观测量来评估全身振动(WBV)造成的不适感。然而,调查有一个缺点,即一些参与者往往以任性的方式表达自己的感受,而加速度数据无法考虑个人喜好和情绪体验。在这项研究中,我们使用随机振动激发的 22 位坐位使用者的脑电图(EEG)来研究振动诱发的精神压力。我们发现,加速度和脑电信号之间存在很强的相关性,这就像脑电图中的伪影,因此我们使用自适应滤波器将其去除。去除伪像后,我们使用地形图分析了脑电波的特征,发现在静态和振动条件下,前额电极检测到的脑电波活动存在显著差异。此外,我们还对额叶电极的额叶α不对称(FAA)和相对频带功率指数进行了统计分析,以评估 WBV 条件下的精神压力。随着振动水平的增加,前额电极的脑电图分析显示 FAA 和阿尔法功率有所下降,但伽马功率有所上升。这些结果与文献中的结论非常吻合,即随着压力的增加,FAA 和阿尔法波段的功率会降低,从而证明 WBV 会导致精神压力,并且压力会随着振动水平的增加而增加。对 WBV 期间压力的脑电图评估有望与现有的自我报告和加速度方法一起用于评估乘坐舒适性。

Removal of movement artifacts and assessment of mental stress analyzing electroencephalogram of non-driving passengers under whole-body vibration
The discomfort caused by whole-body vibration (WBV) has long been assessed using subjective surveys or objective measurements of body acceleration. However, surveys have the disadvantage that some of participants often express their feelings in a capricious manner, and acceleration data cannot take into account individual preferences and experiences of their emotions. In this study, we investigated vibration-induced mental stress using the electroencephalogram (EEG) of 22 seated occupants excited by random vibrations. Between the acceleration and the EEG signal, which contains electrical noise due to the head shaking caused by random vibrations, we found that there was a strong correlation, which acts as an artifact in the EEG, and therefore we removed it using an adaptive filter. After removing the artifact, we analyzed the characteristics of the brainwaves using topographic maps and observed that the activities detected in the frontal electrodes showed significant differences between the static and vibration conditions. Further, frontal alpha asymmetry (FAA) and relative band power indices in the frontal electrodes were analyzed statistically to assess mental stress under WBV. As the vibration level increased, EEG analysis in the frontal electrodes showed a decrease in FAA and alpha power but an increase in gamma power. These results are in good agreement with the literature in the sense that FAA and alpha band power decreases with increasing stress, thus demonstrating that WBV causes mental stress and that the stress increases with the vibration level. EEG assessment of stress during WBV is expected to be used in the evaluation of ride comfort alongside existing self-report and acceleration methods.
