Abstract Parts energy of nonlinear system such as the closed detached response (CDR), primary response (PR), closed detached voltage (CDV), and primary voltage (PV) are resultant of the resonance response interaction and represent their corresponding dynamic characteristics. In this paper, we proposed a promising novel device by integrating a lever-type nonlinear energy sink (LNES) and a levitation magnetoelectric energy harvester (LMEH), to discover the effects of CDR, PR, CDV, and PV on the vibration isolation and energy harvesting. In nonlinear energy harvesting, the weight of the system plays a vital role in improving the accuracy, and hence it cannot be neglected. The root mean square is used to evaluate vibration control and energy harvesting. We used the method of harmonic balance to trace the CDR, PR, CDV, and PV of the system, and numerical results support the harmonic solutions. Specifically, the CDV dramatically increases the voltage of the system. The performance of vibration isolation and energy harvesting has been discussed in terms of the attached mass, nonlinear stiffness, and fulcrum location. Finally, with an appropriate fulcrum location, the performance of LNES-LMEH is compared with the traditional NES-LMEH.

一种使用杠杆增强非线性能量汇和悬浮磁电能量收集器集成的振动能量收集吸收器

摘要 非线性系统的部分能量，如闭合分离响应（CDR）、一次响应（PR）、闭合分离电压（CDV）和一次电压（PV）是共振响应相互作用的结果，代表了它们相应的动态特性。在本文中，我们通过集成杠杆式非线性能量汇 (LNES) 和悬浮磁电能量收集器 (LMEH) 提出了一种很有前景的新型器件，以发现 CDR、PR、CDV 和 PV 对隔振和振动的影响。能量收集。在非线性能量收集中，系统的权重对提高精度起着至关重要的作用，因此不可忽视。均方根用于评估振动控制和能量收集。我们使用谐波平衡的方法来追踪系统的CDR、PR、CDV和PV，和数值结果支持调和解。具体来说，CDV 会显着增加系统的电压。已经根据附加质量、非线性刚度和支点位置讨论了隔振和能量收集的性能。最后，通过适当的支点位置，将 LNES-LMEH 的性能与传统的 NES-LMEH 进行比较。
