Abstract

Abstract: Aiming at the issues of drivers fatigue caused by working environment of monorail cranes in underground transportation, an analysis method of drivers operating comfort was presented based on biomechanics simulation and surface electromyography experiments. A driver-operating system biomechanics coupling model was constructed by Anybody, and the fatigue characteristics of the drivers during operation were quantitatively analyzed. The results show that the average muscle activation of biceps brachii is as 0.171, with the maximum muscle force of 106.9 N, while the muscle activation of gastrocnemius is as 0.288, with the maximum muscle force of 235.6 N； the overall fatigue level of the driver's lower limbs is greater than that of the upper limbs. The accuracy of the simulation results was verified by EMG experiments. The relative error is less than 15%, and the correlation coefficients all are more than 0.966(P < 0.05).

Key words: monorail crane driver, surface electromyography signal, biomechanics, muscle activation

摘要： 针对单轨吊车井下运输的工作环境易导致司机驾驶疲劳的问题，提出了基于生物力学仿真和表面肌电实验的驾驶员操作舒适性分析方法。通过Anybody构建了驾驶员操作系统生物力学耦合模型，并对驾驶员操作过程中的疲劳特性进行了量化分析，结果表明：肱二头肌的肌肉激活度均值为0.171，肌肉力最大为106.9 N；腓肠肌的肌肉激活度为0.288，肌肉力最大为235.6 N；司机下肢整体疲劳程度大于上肢。肌电实验验证了仿真数据的准确性，相对误差小于15%，相关系数均超过0.966（P＜0.05）。
