【摘要】：为分析单手拉车作业肌肉疲劳情况,设计并完成模拟静态手拉叉车试验:通过测量拉车前后单臂拉力的变化及最大耐受时间(MET),记录基于Borg CR-10主观疲劳评分表(RPE)的身体疲劳度,探讨负荷和身体质量指数(BMI)对MET、剩余拉力、力量衰减程度和RPE的影响;并基于试验数据构建单手拉车作业肌肉疲劳MET预测方程。试验结果表明,仅负荷显著影响MET;所构建的以指数函数和幂函数为基础的MET方程与现有方程具有一致性;用所建方程得到的预测值与实测值偏差优于用现有MET方程得到的结果。
[Abstract]:In order to analyze the muscle fatigue of single hand pulling vehicle, the experiment of simulating static hand pull forklift was designed and completed. The change of single arm tension and the maximum endurance time (MET),) were measured before and after pulling the car. Body fatigue was recorded based on Borg CR-10 subjective fatigue scale (RPE), and the influence of (BMI) on MET, residual tension, strength attenuation and RPE was investigated. Based on the experimental data, the MET prediction equation of muscle fatigue in single hand pulley was constructed. The experimental results show that the MET equation based on exponential function and power function constructed by MET; is consistent with the existing equation. The deviation between the predicted value and the measured value obtained from the established equation is better than that obtained from the existing MET equation.
