拖拉机座椅振动对驾驶员腰部疲劳影响研究_以积分肌电值和主观感受评价（Study on driver fatigue evaluation _ waist effect of tractor seat vibration to iEMG and subjective feelings） Study on driver fatigue effect _ waist tractor seat vibration to iEMG and subjective evaluation of.Txt if you see the shadow in front, do not be afraid, it is because the sun behind you! I allow you to walk into my world, but never allow you to walk around in my world. 2011 Research on Agricultural Mechanization in January 1 Research on the influence of tractor seat vibration on drivers waist fatigue The integral EMG value and subjective feeling evaluation value were used as indexes Liu Jun, Kong Degang, Liu Liyi, Zhang Yingwei (School of engineering, Northeast Agricultural University, Harbin) One hundred and fifty thousand and thirty ) Abstract: in order to solve the effect of the tractor seat vibration on the drivers waist fatigue, the vibration state of the tractor during the operation was simulated at different vibration accelerations The sEMG signals of the lumbar, multi lobed and erector muscles were measured under the influence of frequency (sEMG) and analyze its integral electromyography IEMG Changes Law。 The result shows Of the lumbar multiple and erector muscles IEMG at a vibration frequency of 4. Under the condition of 0Hz, the vibration acceleration increases with the increase of Two 0m/s Maximum value occurs at 2 At an acceleration of 1. 2m/s Under the condition of 2, with the increase of vibration frequency, the change is little The lumbar muscles of the drivers subjective feelings The fatigue of meat increases with the increase of vibration acceleration and frequency.
