摘　　要：针对当前大健康需求,开展基于人体生物力学的消防人员穿戴专用消防水枪外骨骼的分析,为减小消防人员职业损伤提供具有普遍意义的理论参考。设计并组织消防人员穿戴和未穿戴专用消防水枪外骨骼的模拟试验,获得消防人员在工作状态下的身体动作信息,分析在工作状态下消防人员在穿戴和未穿戴消防水枪外骨骼时的肌肉活动情况和关节反作用力。与未穿戴外骨骼时相比,穿戴外骨骼时,右边肩背部肌肉激活度明显下降,左边肌肉激活度略微上升,两边肌肉激活度趋于平衡,避免了单侧肌肉过度疲劳。同时,穿戴外骨骼时,消防水枪外骨骼对于左侧下肢关节受力情况有所改善,水枪单侧放置导致下肢关节力矩均略微增加,但右边盂肱关节反作用力下降。In view of the current health needs,the analysis of the exoskeleton of firefighters fire water guns based on human biomechanics is carried out to provide a theoretical reference of universal significance to reduce the occupational injury of firefighters.Design and organize the simulation experiment under the test conditions of firefighters with fire water gun wearing and not wearing the exoskeleton,obtain the body movement information of firefighters under the working condition,and analyze the muscle activity and joint reaction force of firefighters wearing and not wearing the exoskeleton under the working condition.Compared with those without the exoskeleton,when the exoskeleton is worn,the activation degree of the right shoulder and back muscles decreases significantly,while the activation degree of the left muscles increases slightly,and the activation degree of both muscles tends to be balanced to avoid unilateral muscle fatigue.At the same time,when wearing the exoskeleton,the stress of the fire water gun exoskeleton on the left lower limb joint was improved.The unilateral placement of the water gun led to a slight increase in the lower limb joint torque,but the reaction force of the right glenohumeral joint decreased.
