基于反应运动时的风力灭火机作业疲劳研究
Study on operating fatigue using pneumatic extinguishers based on reaction time and motion time
6MF-30型风力灭火机是我国森林灭火作业中常用的个人作业机型。为了研究风力灭火机作业对人体疲劳的影响，本文进行了模拟灭火作业实验，并且分析了背负姿势、作业动作对操作者反应时间和运动时间的影响。结果表明，模拟灭火后操作者反应时间受作业动作方式的影响显著（p<0.05），摆动灭火比固定方向灭火引起的反应时间增加比率大；左臂运动时间受作业背负方式的影响显著（p<0.05），左肩斜挎时运动时间增加比最小，引起的左臂作业负荷最小。
6MF-30 portable pneumatic extinguishers are widely used personal fire-fighting tools during the forest fire-fighting tasks in China. In order to acquire the impact of fire-fighting task using pneumatic extinguisher on operating fatigue, a laboratory study on simulative fire-fighting tasks was conducted. The impact of carrying posture and motion on reaction time and motion time was analyzed. The impact of motion on the reaction time is significant（p<0.05）. The value of growth ratio of reaction time with the motion of swaying is higher than that of fixation. The carrying posture has a significant impact on the motion time（p<0.05）, with the highest values in the posture of left shoulder carrying.
