摘要
目的本文分析军事领域连续键盘输入作业过程中操作者疲劳发生状况及特点。方法通过应用问卷调查方法,分析操作者疲劳发生趋势和主要症状;应用计算机仿真方法,评估操作者肌肉骨骼系统不适的具体发生位置。结果 (1)作业过程中操作者体力疲劳和脑力疲劳并存,且随着作业时间延长呈现出显著加重的单调趋势;(2)肌肉骨骼系统不适及疲劳主要集中在肩周、腕部、上臂及躯干部位。结论军事领域连续键盘输入作业特点决定了操作者疲劳是全面、单调显著加重的,且疲劳发生累计容易导致操作者肌肉骨骼系统损伤,因此,需要积极采取疲劳预防及对抗措施。
Objective To analyze the fatigue characteristics of operators in continuous typing task through keystroke.Methods Questionnaires were applied to investigate the fatigue trend and main symptoms and computer simulation were used to evaluate the specific areas of musculoskeletal discomfort.Results （1） Physical fatigue and mental fatigue coexist during the typing task,and the fatigue symptoms of operators become more serious following the prolonged task.（2） The musculoskeletal discomfort of operators occurs mostly on shoulder portion,wrist,upper arm and lumbar muscles.Conclusion The features of continuous typing task in military domain result in the fatigue characteristics of operators,and cumulative fatigue can easily lead to musculoskeletal disorders.Effective measures of fatigue prevention are necessary for these operators.
