This paper presents the process optimization of some key parameters, such as beam spacing, flux density and optimal impedance load matching of magnetic coupled piezoelectric harvesters. In order to do this, the distributed parameters model of this structure, containing macro-fiber components (MFC) with homogenous material in the piezoelectric fiber layer, was determined. Next, the computational model of this structure was designed on the basis of the first-order shear theory (FOST). The performed analysis of the calculated voltage outputs on the basis of the theoretical approach and finite element model by various beam spacing allowed us to indicate that optimized parameters play an important role in enhancing the efficiency of the system. Experiments carried out in a laboratory stand for this structure, allowed for the verification of the numerical results. In the effect, it can be noted that magnetic coupled harvesters will be relevant for a wide range of application sectors, as well as useful for the evolving composite industry.
本文介绍了磁耦合压电能量采集器的一些关键参数的工艺优化，如梁间距、通量密度和最佳阻抗负载匹配。为此，确定了该结构的分布参数模型，该模型包含在压电纤维层中具有均匀材料的宏观纤维组件（MFC）。接下来，基于一阶剪切理论（FOST）设计了该结构的计算模型。通过对不同梁间距下基于理论方法和有限元模型计算出的电压输出进行分析，我们发现优化参数在提高系统效率方面起着重要作用。在实验室试验台上对该结构进行的实验验证了数值结果。结果表明，磁耦合能量采集器将适用于广泛的应用领域，对不断发展的复合材料行业也很有用。
