The paper presents a model of a chiral multi-structure incorporating gyro-elastic beams. Floquet-Bloch waves in periodic chiral systems are investigated in detail, with the emphasis on localization and the formation of standing waves. It is found that gyricity leads to low-frequency standing modes and generation of stop-bands. A design of an earthquake protection system is offered here, as an interesting application of vibration isolation. Theoretical results are accompanied by numerical simulations in the time-harmonic regime.
本文提出了一种包含陀螺弹性梁的手性多结构模型。详细研究了周期性手性系统中的弗洛凯 - 布洛赫波，重点关注局域化和驻波的形成。研究发现，回转性会导致低频驻波模式和带隙的产生。本文给出了一种地震保护系统的设计，作为隔振的一个有趣应用。理论结果伴有时间谐波 regime 下的数值模拟。 （注：此处“time-harmonic regime”不太明确准确意思，可结合更专业背景理解，直译为“时间谐波 regime” ）
