Abstract

In view of the collection of vibration energy generated by omnidirectional vibration devices such as washing machine, a new method of electromagnetic vibration power generation based on washing machine is proposed. The physical model of closed magnetic circuit is established by using spring, permanent magnet, winding coil and square frame. The mathematical model and theoretical derivation are carried out according to the relevant laws of electromagnetic induction, and the physical model is obtained. Combined with the software of COMSOL multiphysics, the finite element method is used to simulate the model. In the simulation process, the magnetic field and voltage state of one side of the square frame are transformed into two-dimensional images due to the characteristics of axisymmetry; the parameters are set, the magnetic field and mathematical field are established to obtain the steady-state solution; the transient solution is obtained by grid thinning. The simulation results are consistent with the calculation results, which proves that the electromagnetic vibration power generation method realized in this paper is feasible.

一种基于洗衣机的电磁振动发电方法

针对洗衣机等全向振动装置产生的振动能量的收集，提出了一种基于洗衣机的电磁振动发电新方法。采用弹簧、永磁体、线圈、方框等建立了闭合磁路的物理模型。根据电磁感应的相关规律，建立了数学模型并进行了理论推导，得到了物理模型。结合COMSOL多物理场软件，采用有限元法对模型进行仿真。在仿真过程中，利用轴对称的特性，将方框一侧的磁场和电压状态转换为二维图像;设置参数，建立磁场和数学场，得到稳态解;通过网格细化得到暂态解。仿真结果与计算结果一致，证明了本文实现的电磁振动发电方法是可行的。
