土木工程结构的双层多重调谐质量阻尼器控制策略

为能得到用尽可能少的调谐质量阻尼器(TMD)组成有效性和鲁棒性高的多重调谐质量阻尼器控制系统，本文提出了一种适用于土木工程结构的新控制策略——双层多重调谐质量阻尼器(DMT—MD)。使用定义的优化目标函数，评价了双层多重调谐质量阻尼器(DMTMD)的控制性能。数值结果表明，双层多重调谐质量阻尼器(DMTMD)比多重凋谐质量阻尼器(MTMD)具有更好的有效性和对频率调谐的鲁棒性。DMTMD比双重调谐质量阻尼器(DTMD)具有更好的有效性，而DMTMD和DT—MD对频率调谐的鲁棒性近似相同。因此，双层多重调谐质量阻尼器是一种先进的结构控制策略。

Dual-layer multiple tuned mass damper control strategy of civil engineering structures

To get the multiple tuned mass dampers with high effectiveness and robustness using less tuned mass dampers (TMD), the new control strategy of the dual-layer multiple tuned mass dampers (DMTMD) is proposed to attenuate undesirable oscillations of civil engineering structures under the ground acceleration. With resorting to the goal function defined for the optimum searching, the parameter studies were performed to evaluate the control performance of the DMTMD. The results indicate that the DMTMD provides better effectiveness and robustness to the change in the frequency tuning than the multiple tuned mass dampers (MTMD) with equal total mass. Likewise, the DMTMD has better effectiveness than the dual tuned mass dampers (DTMD), while practically keeps the same robustness to the change in the frequency tuning as the DTMD. Therefore, the DMTMD is an advanced control strategy for the suppression of undesirable vibrations of civil engineering structures.
