摘　　要：单轨吊车作为一种煤矿井下运输机车,其工作环境会引发井下操作人员工作的舒适性等问题。为分析单轨吊驾驶员主要肌肉的疲劳状况,对易疲劳的16块肌肉进行肌电测试研究,并提取信号的积分肌电值(iEMG)和均方根值(RMS),结合时域分析和多元非线性回归分析方法,以iEMG和RMS为自变量,疲劳度为因变量分析肌肉疲劳特性。结果表明:驾驶员在上车和下车过程中的肌肉疲劳度远大于机车行走时的肌肉疲劳度;在机车操作过程中,由于驾驶员需要一直用右脚踩踏加速踏板来控制机车行走,使驾驶员右侧下肢肌肉中的股直肌、股二头肌、腓肠肌和比目鱼肌产生疲劳,且腓肠肌的疲劳度最大;为避免驾驶员出现一侧肌肉过度疲劳的情况,应该将驾驶室操作元件布置在两侧,减少一侧肌肉的使用率,降低驾驶员操作疲劳度,提高驾驶舒适度。As a kind of underground transportation locomotive in coal mine,the working environment of monorail crane will cause problems such as the comfort of underground operators.In order to analyze the fatigue status of the main muscles of the monorail crane driver,the EMG tests were carried out on 16 muscles that were prone to fatigue,and the integrated EMG value(iEMG)and root mean square value(RMS)of the signal were extracted.Combined with time domain analysis and multiple nonlinear regression analysis methods,iEMG and RMS were used as independent variables,and fatigue was used as dependent variable to analyze muscle fatigue characteristics.The results show that the muscle fatigue of the driver in the process of getting on and off is much greater than that of the locomotive walking.In the process of locomotive operation,because the driver needs to use his right foot to stamp on the accelerator pedal to control the locomotive walking,the rectus femoris,biceps femoris,gastrocnemius and soleus muscles in the right lower limb muscles of the driver are fatigued,and the fatigue of the gastrocnemius muscle is the largest.In order to avoid the driver's excessive fatigue of one side of the muscle,the cab operating elements should be arranged on both sides to reduce the utilization rate of one side of the muscle,reduce the driver's operating fatigue and improve the driving comfort.
