在这篇文章中,我们研究了一个能量采集器关于其最佳阻抗负载。风能采集器表现出三种不同类型的振荡:单井(关于稳定平衡)、跨井(威尔斯之间)和井间(关于不稳定平衡)。发生的振荡类型取决于例如激励参数和初始条件。已经观察到([1]),允许最大化功率输出的最佳阻抗对于每种振荡类型而变化。在我们的调查中,我们补充这些研究结果与分析和数值计算。对于我们的分析,我们检查了能量收集器的无量纲耦合方程。(© 2015 Wiley‐VCH Verlag GmbH & Co. KGaA,魏因海姆)
In this contribution we investigate a bistable energy harvester with regard to its optimal impedance load. A bistable energy harvester exhibits three different types of oscillation: Single‐well (about a stable equilibrium), cross‐well (between the wells) and inter‐well (about the unstable equilibrium). The occurring oscillation type depends, for instance, on the excitation parameters and the initial conditions. It has already been observed ( [1]) that the optimal impedance, which allows to maximize the power output, varies for each oscillation type. In our investigations we complement these findings with analytical and numerical calculations. For our analysis we examine the non‐dimensionalized coupled equations of a bistable energy harvester.
