提高基于振动的能量采集器带宽的一个可行方法是利用非线性振荡器的频率响应。在文献中，有一些关于具有非线性振荡器的共振式能量收集器的工作。在大多数这些工作中，收割机为纯阻性负载提供动力。考虑到非线性能量收集器的复杂行为，很难确定这类设备的最佳负载。这项工作的目的是在纯阻性负载的情况下找到非线性能量收集器的最优负载。在对具有硬化柔度的非线性能量采集进行分析的基础上，介绍了一种基于数值延拓的方法，该方法可用于在已知器件特性和激励的情况下寻找最优负载。
A viable way to increase the band-width of a vibration-based energy harvester is exploiting the frequency response of non-linear oscillators. In the literature there are several works on resonating energy harvesters featuring non-linear oscillators. In the majority of these works, the harvester powers purely resistive loads. Given the complex behaviour of non-linear energy harvesters, it is difficult to identify the optimum load for these kind of devices. The aim of this work is to find the optimal load for a non-linear energy harvester in the case of purely resistive loads. The work, following the analysis of a non-linear energy harvesting with hardening compliance, introduces a methodology based on numerical continuation which can be used to find the optimum load once the characteristics of device as well as the excitation is known.
