摘要

本文提出了一种新型涡流调谐串联质量阻尼器-插入器(简称 EC-TTMDI),建立了振动控制机制的理论分析模型,并利用智能优化算法进行了参数化分析和设计。该模型为带有 EC-TTMDI 的单自由度(SDOF)结构,受到高斯白噪声基本激励。具体来说,首先利用电涡流阻尼器(ECD)的等效线性化和残差定理得到了 SDOF 结构-EC-TTMDI 系统的位移方差表达式。然后将优化目标函数定义为位移方差最小化,位移方差是白噪声强度与模型传递函数 H2 准则平方的乘积。采用模式搜索算法,对目标函数的变化趋势和最佳设计参数进行了仔细研究。然后,从控制效果、鲁棒性、结构频率响应、抑制带宽和行程等方面揭示了 EC-TTMDI 的减振机理。最后,对 SDOF 结构-EC-TTMDI 系统进行了近场脉冲、近场非脉冲和远场地震的时间历程响应分析,进一步证实了 EC-TTMDI 的性能优越性。结果表明,与 TTMDI 和 TMDI 相比,EC-TTMDI 具有更高的鲁棒性和更好的控制效果。此外,EC-TTMDI 还具有阻尼力限制特性,从而提高了 TTMDI 的完整性和可靠性。

High robust eddy current tuned tandem mass dampers-inerters for structures under the ground acceleration
In this work, a novel eddy current tuned tandem mass dampers-inerters, referred to as EC-TTMDI is proposed, a theoretical analysis model of the vibration control mechanism is established, and parameterized analysis and design are conducted using the intelligent optimization algorithm. This model is the single-degree-of-freedom (SDOF) structure with EC-TTMDI subjected to Gaussian white noise base excitation. Specifically, the expression for the displacement variance of the SDOF structure-EC-TTMDI system was firstly obtained with resorting to both the equivalent linearization of eddy current damper (ECD) and residue theorem. The optimization objective function was then defined as minimization of the displacement variance, which is product of the white noise intensity and the square of H2 norm of the model transfer function. Employing the pattern-search algorithm, the variation trends of the objective function and the optimum design parameters were subsequently scrutinized. The vibration damping mechanism of EC-TTMDI is then revealed in terms of control effectiveness, robustness, structural frequency response, suppression bandwidth, and stroke. Finally, the time history response analysis of the SDOF structure-EC-TTMDI system subjected to the near-field impulse, near-field non-impulse, and far-field earthquakes was conducted to further confirm the performance superiority of EC-TTMDI. Results demonstrates that EC-TTMDI offers higher robustness and better control effectiveness compared to TTMDI and TMDI. Furthermore, EC-TTMDI features the damping force limiting characteristic, which enhances the integrity and reliability of TTMDI.

期刊介绍: The journal aims to encourage and enhance the role of mechanics and other disciplines as they relate to earthquake engineering by providing opportunities for the publication of the work of applied mathematicians, engineers and other applied scientists involved in solving problems closely related to the field of earthquake engineering and geotechnical earthquake engineering. Emphasis is placed on new concepts and techniques, but case histories will also be published if they enhance the presentation and understanding of new technical concepts.
