摘要
振动发电就是利用电磁感应、压电技术、智能材料等将外部的机械振动能量通过一定装置转换成电能,实现机械振动能量和电能的转换。在分析磁控形状记忆合金(Magnetic Shape Memory Alloy,简称MSMA)振动发电原理的基础上,利用MSMA智能材料的维拉利效应对振动能量进行收集,建立了MSMA振动发电机的数学模型,求出振动发电机感应电动势与压应力及外加磁场的数学关系。分析了振动应力幅值、频率的响应特性,仿真结果验证了MSMA振动发电的可行性。
Vibration-based power generation is to convert the external mechanical vibration energy into elec- trical energy with the use of electromagnetic induction, piezoelectric technology and smart materials. Based on the analysis of the vibration generation principle of magnetic shape memory alloy (MSMA), vibration en- ergy is collected according to the Villari effect of smart materials MSMA. A mathematical model of MSMA vibration generator is built to find the mathematical relationship between the induced electromotive force of the vibration generator and the compressive stress and applied magnetic field. And the response characteris- tics of the vibration stress amplitude and frequency are analyzed. The simulation results verify the feasibility of MSMA vibration generation.
