Tuned mass dampers (TMDs), in which a reaction mass is attached to a structural system via a spring-parallel-damper connection, are commonly used in a wide range of applications to suppress deleterious vibrations. Recently, a mass-included absorber layout with an inerter element, termed the tuned mass damper inerter (TMDI), was introduced, showing significant performance benefits on vibration suppression. However, there are countless mass-included absorber layouts with springs, dampers and inerters, which could potentially provide more preferred dynamic properties. Currently, because there is no systematic methodology for accessing them, only an extremely limited number of mass-included absorber layouts have been investigated. This paper proposes an approach to identify optimum vibration absorbers with a reaction mass. Using this approach, a full class of absorber layouts with a reaction mass and a pre-determined number of inerters, dampers and springs connected in series and parallel, can be systematically investigated using generic Immittance-Function-Networks. The advan- tages of the proposed approach are demonstrated via a 3 d.f. structure example.
调谐质量阻尼器（TMDs）通过弹簧 - 并联 - 阻尼器连接将一个反应质量块连接到结构系统上，常用于广泛的应用中以抑制有害振动。最近，引入了一种带有惯性元件的包含质量块的吸收器布局，称为调谐质量阻尼器惯性器（TMDI），在振动抑制方面显示出显著的性能优势。然而，存在无数带有弹簧、阻尼器和惯性器的包含质量块的吸收器布局，它们可能潜在地提供更优的动态特性。目前，由于没有用于评估它们的系统方法，仅研究了极少数包含质量块的吸收器布局。本文提出一种方法来识别带有反应质量块的最优减振器。使用这种方法，可以通过通用的导纳函数网络系统地研究一整类带有反应质量块且具有预定数量的惯性器、阻尼器和弹簧以串联和并联方式连接的吸收器布局。通过一个三自由度结构示例展示了所提方法的优势。
