摘要
为实现对自然环境中不同方向振动源的能量收集,提出一种筒状多方向电磁振动发电装置,结合电磁学理论和机械振动学理论,给出了电磁振动发电装置输出电压的理论求解方法,得到外界激励方向和永磁体环是影响装置输出电压主要因素的结论。通过算例分析了外界激励方向和永磁体环结构参数对电磁振动发电装置输出电压的影响,结果表明,随着外界激励方向和永磁体环结构参数的变化,电磁振动发电装置均可产生一定的输出电压,最高输出电压达到2.1 V。
In order to realize the energy harvesting of vibration sources in different directions in the natural environment,a cylindrical multi-directional electromagnetic vibration generator is proposed.Combining the electromagnetic theory with mechanical vibration theory,a theoretical solution method for the output voltage of the electromagnetic vibration generator is given.It is concluded that the external excitation direction and the permanent magnet ring are the main factors affecting the output voltage of the generator.The influence of the external excitation direction and the structural parameters of the permanent magnet ring on the output voltage of the electromagnetic vibration generator is analyzed through a calculation example.The results show that with the change of the external excitation direction and the structural parameters of the permanent magnet ring,the electromagnetic vibration generator can generate a certain output voltage,and the maximum output voltage reaches 2.1 V.
