Passive mechatronic vibration absorbers have demonstrated great performance potential in previous studies. For such devices, optimal design of the electrical circuits therein is critical but challenging since existing techniques have evident limitations: those investigating a few specific circuits leave huge possibilities unexplored; those optimising circuit impedances potentially lead to circuits which cannot be physically implemented. Another challenge lies in the need for considering device parasitic effects (e.g., transducer¹ resistance) to guarantee the predicted performance accuracy—this can be extremely time-consuming, especially when exploring numerous design possibilities (e.g., circuits, transducers). To address these two challenges, this paper proposes a novel design methodology, which (1) allows the optimal and practically implementable circuit to be identified among all layouts with predefined complexity; (2) considers the device parasitic effects where necessary, to efficiently explore various possibilities. The validity of this methodology is demonstrated via an automotive suspension design case study, where the obtained significant performance improvement is successfully verified via experiments. This methodology is directly applicable to vibration suppression of other engineering structures and can also be adopted for other mechatronic absorber types.

被动式机电吸振器在以往的研究中已显示出巨大的性能潜力。对于此类设备，其中电路的优化设计至关重要但具有挑战性，因为现有技术具有明显的局限性：那些研究少数特定电路的人留下了未探索的巨大可能性；那些优化电路阻抗的方法可能会导致无法物理实现的电路。另一个挑战在于需要考虑设备寄生效应（例如，换能器¹电阻）以保证预测的性能准确性——这可能非常耗时，尤其是在探索众多设计可能性（例如，电路、传感器）时。为了解决这两个挑战，本文提出了一种新颖的设计方法，它 (1) 允许在具有预定义复杂度的所有布局中识别最佳且实际可行的电路；(2) 必要时考虑器件寄生效应，以有效探索各种可能性。通过汽车悬架设计案例研究证明了该方法的有效性，其中通过实验成功验证了所获得的显着性能改进。该方法直接适用于其他工程结构的振动抑制，也可用于其他机电减振器类型。
