摘要
为科学管理农机作业系统,运用人机工程学的原理,提出以心率和作业时间综合评价疲劳的方法,对机播作业中拖拉机驾驶员的疲劳程度进行了分析与评价。结果表明：驾驶进口大功率拖拉机驾驶员的心率增加率较低,属于轻级劳动强度,可承受最长作业时间为14.2-15.6h,疲劳综合评价值f在1.21-1.48之间;而驾驶国产东方红1002型拖拉机驾驶员的心率增加率较高,属于中级劳动强度,可承受最长作业时间为12.8h,f为1.79。
In order to manage farm machinery work system scientifically, the principles of ergonomics and a fatigue comprehensive evaluation method by heart rate and work time were proposed, and it was used for evaluating and analysis the tractor driver＇s fatigue in sowing work. The result showed that driving imported large power tractor in sowing work, the heart rate increase ratio is fairly low, and workload lies in light level, maximum acceptable work time （tmax） is between 14.2 h and 15.6 h, fatigue comprehensive assessment value f is between 1.21 and 1.48. While driving domestic Dongfanghong- 1002-tractor, heart rate increase ratio is rather high, workload lies in normal level, tmax is 12.8 h, and f is 1.79. In real operation, the working time of the driver is longer than maximum work time.
