拖拉机驾驶员作业强度对其生理负荷的影响

Influences of the driving intensity on the tractor drivers' physiological load

驾驶拖拉机作业时,驾驶员的作业强度与生理负荷随着拖拉机的转向机构的不同而有较大的差别。该研究基于拖拉机两种不同的转向机构,对被测试人员实际作业时的心率和氧气的消耗量等指标进行测试,获得了不同的转向机构下被测试人员的心理和生理的变化规律。结果表明,被测人员随着不同转向机构其作业的强度也发生了变化。试验结果为设计新型的拖拉机的各系统提供了驾驶人员自身的数据,同时为改进现有的拖拉机的各系统提供重要的理论参考。

When driving a tractor in the field, the operating strength and the physiological load of an operator differ greatly from the steering mechanisms. The number of heart beat and the volume of the oxygen consumption were tested based on the two different steering mechanisms. Then the rule of psychological and physiological changes with the different steering mechanisms was achieved. The results state that the operating load for vohmteers with the different age and driving age varies from the different steering mechanisms. It provides data of operators themselves for designing the each system on a new model and supplies the important theoretical reference to revising the existing system on tractor.
