本文提出可以根据操作者的心率和机械的工作量来相对地衡量操作人力机械时人体的能量消耗率。这一方法是简单的,可用于人力机械的设计过程,也可用来评比同一类型的人力机械。在自制的自行车加载器上进行了试验。心率由心率发射器-接收器系统遥测并记录。测试对象借助于节拍器的指引以稳定的节拍驱动自行车加载器。试验结果表明这一方法是可行的。
This paper proposes that the energy consumption rate of the human body when operating the human-powered machine can be relatively measured according to the operator’s heart rate and the workload of the machine. This method is simple, can be used for human mechanical design process, can also be used to evaluate the same type of human machinery. Experiments were run on homemade bike loaders. Heart rate is telemetered and recorded by the heart rate transmitter-receiver system. The test subject drives the cycle loader with a steady beat with the aid of a metronome. The experimental results show that this method is feasible.
