摘　　要：为了研究背负式林果采摘机的人机工程学特性,通过林果采摘手臂疲劳实验,建立了基于表面肌电信号的上肢肱二头肌疲劳评价模型,并结合心率测试对比分析背负式林果采摘机和手持式采摘机的手臂疲劳特性。结果表明:操作背负式林果采摘机心率增加比小于手持式采摘机;同时手臂疲劳程度也小于手持式采摘机。背负式林果采摘机较手持式采摘机更加省力,能够有效地缓解肌肉疲劳。Ergonomics evaluation of forest-fruit-picking machine is very important to design harvest machinery.In order to study the ergonomic features of knapsack forest-fruit-picking machine,a fatigue evaluation model of upper limb biceps brachii muscle based on surface electromyography（ sE MG） signals was established by arm fatigue test. Combining the heart rate test and the model, the arm fatigue characteristics of the knapsack forest-fruit-picking machine and handheld picking machine were compared. The results showed that increasing ratio of heart rate and fatigue degree with knapsack forestfruit-picking machine were less than those with handheld picking machine in the same situation.Therefore,the knapsack forest-fruit-picking machine is more labor-saving than the handheld picking machine,and can effectively relieve muscle fatigue.
