It first summarizes the research status of vibration and noise reduction, and research progress in phononic crystals and acoustic metamaterials. Based on this, one-dimensional periodic beam, two-dimensional thin plate with circular hole, and corresponding gradient structures are introduced, and their dynamic characteristics are discussed in detail. Therefore, different equivalent methods for different models are proposed through theoretical analysis, modal analysis and transmission rate analysis. Finally, a Helmholtz-type acoustic metamaterial, i.e. a multi-layer slotted tube acoustic metamaterial, is studied. Aiming at the low-frequency band gap of this model, a theoretical model for solving the inverse problem of acousto-electric analogue equivalent is proposed, and the effect of structural parameters on the low-frequency band gap is studied using this equivalent model. ..This book closely revolves around how to conduct equivalent | | 出版日期 | Book 2022 | | 关键词 | Acoustic Metamaterials; Dispersion relation; Periodic sheet construction; Gradient bar construction; Aco | | 版次 | 1 | | doi | https://doi.org/10.1007/978-981-19-4371-3 | | isbn_softcover | 978-981-19-4373-7 | | isbn_ebook | 978-981-19-4371-3 | | copyright | Publishing House of Electronics Industry 2022 |
