摘要
为了了解拖拉机驾驶员颈部的疲劳状况,在模拟拖拉机作业过程基础上,对驾驶员颈部胸锁乳突肌的表面肌电信号进行了测试分析,并以积分肌电值与平均功率频率为评价指标,对作业过程中驾驶员颈部疲劳进行了研究。结果显示:头部转动角度对积分肌电值和平均功率频率有明显影响,积分肌电值随角度的增大呈现明显的增长趋势,平均功率频率随角度的增加呈现明显下降趋势,表明大角度的头部转动容易使拖拉机驾驶员颈部产生疲劳。同时,分析了拖拉机驾驶员颈部产生肌肉疲劳的原因,提出了缓解疲劳的建议。
In order to understand the change of tractor drivers＇ neck muscle inoperation, this paper tested and analyzed the electromyogram signal of neck muscle based on simulating the process of work, and maked a study of neck muscle by using integrated electromyogram and mean power frequency as index. The results show： the angle of turning head had significantly impact on iEMG and MPF. With the angle of the increasing, the iEMG showed a growing trend;the MPF showed a downward trend. This paper also analyzed the causes of neck muscle fatigue and make recommendations to alle-viate fatigue.
