一段时间以来，利用人体运动来收集能量一直是一个流行的想法。提出的许多方法可能会让人不舒服，或者对人的步态造成重大负担。为了研究悬载背包对人体步态的影响，本文采用了能量收集背包的硬件在环模拟器。这个想法是基于一个悬浮负载产生的能量，当一个人走路时，悬浮负载在背包上垂直移动。当这种线性系统产生的能量与人的行走频率产生共鸣时，能量可以最大化。然而，这样的配置也会对用户的背部施加很大的力。本文提出的系统是由一个附着在背包上的质量块组成的，该质量块由电机控制，以模拟悬载背包。这种设置的优点是能够测试不同的设置，关于弹簧刚度或阻尼系数，背包收集器，并研究它们对能量收集潜力的影响，以及对人类步态的影响。本文描述了在九名男性志愿者的帮助下，在跑步机上对该系统进行测试的初步结果和分析。
Exploiting human motion for the purpose of energy harvesting has been a popular idea for some time. Many of the approaches proposed can be uncomfortable or they impose a significant burden on the person's gait. In the current paper a hardware in-the-loop simulator of an energy harvesting backpack is employed in order to investigate the effect of a suspended-load backpack on the human gait. The idea is based on the energy produced by a suspended-load which moves vertically on a backpack while a person walks. The energy created from such a linear system can be maximised when it resonates with the walking frequency of the person. However, such a configuration can also cause great forces to be applied on the back of the user. The system which is presented here consists of a mass attached on a rucksack, which is controlled by a motor in order to simulate the suspended-load backpack. The advantage of this setup is the ability to test different settings, regarding the spring stiffness or the damping coefficient, of the backpack harvester, and study their effect on the energy harvesting potential, as well as on the human gait. The present contribution describes the preliminary results and analysis of the testing of the system with the help of nine male volunteers who carried it on a treadmill.
