LIGHTWEIGHT STRUCTURAL CONTROL BASED ON TUNED MASS INERTER SYSTEM (TMIS) UNDER TYPICAL EXCITATION

  • 摘要: 经典调谐质量减振系统往往需要较大的附加质量和相应的额外安装空间,为其实际使用带来不便。惯容系统是一种新型的高效振动控制装置,具有两端点惯性、表观质量增效和耗能增效等特性,其中表观质量增效特性可以实现轻量化结构振动控制。该文聚焦具有轻量化控制特征的广义调谐质量惯容减振系统(Tuned mass inerter system, TMIS),陈述其基本原理与典型拓扑形式。考虑地震作用、风荷载与人致激励三种典型动力激励,提出适用于广义TMIS的基于性能需求的优化设计方法获得惯容系统的参数,在使结构满足性能目标的同时降低所需调谐质量的大小。通过与经典调谐质量减振系统进行对比,说明调谐质量惯容系统的轻量化减振控制优势,并通过典型案例及其动力响应分析加以验证。研究表明:TMIS是一种高效的结构振动控制装置,在多种典型灾害下均能有效实现结构减振控制的性能目标与减小调谐质量需求的轻量化目标,为结构振动控制问题的解决提供了便利的新选择。

     

    Abstract: Classical tuned mass vibration control systems often require large additional mass and installation space, which is inconvenient in common use. Inerter system is a high-efficiency vibration control system with the characteristic of two-terminal inertia, apparent mass enhancement and damping enhancement, among which the apparent mass enhancement characteristic can realize lightweight structural vibration control. This research focuses on a generalized tuned mass inerter system (TMIS) with lightweight characteristic, and explains its basic theory and typical topology. A demand-based optimal design method is proposed to determine the parameters of the vibration control systems, aiming at reducing the required additional mass as well as meeting the structural performance demand. Three typical external excitations are considered in this research, including seismic effect, wind load and human-induced excitation. The lightweight advantage of the proposed TMIS is illustrated through a comparison with the classical tuned mass damper, and structural case study with dynamic response analysis is conducted to verify the control effect. The results show that TMIS is an efficient structural vibration control system, which can effectively mitigate the structural dynamic response under different types of typical external excitations, and lightweight the required additional tuned mass. TMIS provides an alternative vibration suppression device and is convenient for structural design and installation.
