Abstract

The paper introduces a novel active-passive integrated vibration isolator based on metal rubber and piezoelectric actuator, along with an adaptive active vibration control strategy. The active control strategy employs the adaptive dynamic step filtered-x normalized least mean squares algorithm, allowing the step size to adaptively adjust with the error. The secondary control path of the algorithm is modeled using the enhanced rate-dependent Prandtl–Ishlinskii model and the auto-regressive with extra inputs model. The active-passive integrated vibration isolator achieves broadband vibration isolation from 10 to 200 Hz. Compared to passive isolation, the transmissibility decreases from 0.99 to 0.056 at 10 Hz, from 3.02 to 0.068 at the resonance frequency, and from 0.057 to 0.046 at 200 Hz. This study provides a theoretical and experimental foundation for the design of a novel, broadband, and efficient active-passive integrated vibration isolator structure and active control method.

基于金属橡胶和压电致动器的主被动一体化隔振器研究
本文介绍了一种基于金属橡胶和压电致动器的新型主被动一体化隔振器,以及一种自适应主动振动控制策略。该主动控制策略采用自适应动态步长滤波-x 归一化最小均方差算法,允许步长随误差自适应调节。该算法的二级控制路径采用了增强型速率相关普兰德-伊什林斯基模型和带有额外输入的自动回归模型。主动-被动一体化隔振器实现了 10 至 200 Hz 的宽带隔振。与被动隔振相比,传递率在 10 Hz 时从 0.99 降至 0.056,在共振频率时从 3.02 降至 0.068,在 200 Hz 时从 0.057 降至 0.046。这项研究为设计新型、宽带、高效的主被动一体化隔振器结构和主动控制方法提供了理论和实验基础。

期刊介绍: Smart Materials and Structures (SMS) is a multi-disciplinary engineering journal that explores the creation and utilization of novel forms of transduction. It is a leading journal in the area of smart materials and structures, publishing the most important results from different regions of the world, largely from Asia, Europe and North America. The results may be as disparate as the development of new materials and active composite systems, derived using theoretical predictions to complex structural systems, which generate new capabilities by incorporating enabling new smart material transducers. The theoretical predictions are usually accompanied with experimental verification, characterizing the performance of new structures and devices. These systems are examined from the nanoscale to the macroscopic. SMS has a Board of Associate Editors who are specialists in a multitude of areas, ensuring that reviews are fast, fair and performed by experts in all sub-disciplines of smart materials, systems and structures. A smart material is defined as any material that is capable of being controlled such that its response and properties change under a stimulus. A smart structure or system is capable of reacting to stimuli or the environment in a prescribed manner. SMS is committed to understanding, expanding and dissemination of knowledge in this subject matter.
