摘　　要：为收集人体运动中的振动能量,基于惯容元件设计了嵌入背包的电磁式能量收集装置.该装置有助于提升人体舒适度、解决传统俘能装置阻尼匹配困难的问题.在建立数学模型和调研人体步态特征的基础上,根据机电比拟法和最大功率传输定理分析装置的能量传输效率,同时考虑人体承担该装置的载荷.结果表明,惯容元件的引入为系统参数选取增加了一个自由度,可以有效调节俘能装置的固有频率与人体振动频率相匹配,实现能量收集效率的最大化,同时有效减轻人体的承重负担.最后,在基于人体关节活动机理和遗传算法构建的仿真平台上对理论分析进行验证,证实了所提方法的有效性.In order to collect continuous and readily available human vibration energy,an electromagnetic energy-harvesting device embedded in a backpack is proposed based on the inerter component.The device also aims to enhance human comfort and overcome the challenge of damping matching in traditional energy harvesting devices.The energy transfer efficiency of the device was analysed using force-electricity analogy and the maximum power transfer theorem.The impact of the device on the load experienced by the human body was also taken into consideration by establishing mathematical models and researching human gait characteristics.The findings suggest that the device can enhance the efficiency of human vibration energy collection by introducing a new degree of freedom that enables effective adjustment of the system’s natural frequency to match the human vibration frequency.Additionally,selecting appropriate inertance can significantly reduce the biomechanical load on the human body.Finally,the theoretical analysis was validated through a simulation platform based on the mechanism of human joint movement and a genetic algorithm,confirming the effectiveness of the proposed approach.
