摘要
提出了双层多重调谐质量阻尼器(DMTMD)和多重双重调谐质量阻尼器(MDTMD)控制策略。利用定义的优化目标函数,评价了最易制作DMTMD和MDTMD模型的性能。数值结果表明,DMT-MD和MDTMD比基于任意整数或基于奇数的多重调谐质量阻尼器(AI-MTMD和ON-MTMD)具有更好的有效性和鲁棒性。MDTMD和DMTMD具有近似相同的有效性,但MDTMD比DMTMD具有更好的鲁棒性。总的来说,MDTMD的冲程大于DMTMD的冲程;DMTMD中小质量块的冲程大于AI-MT-MD和ON-MTMD的冲程。
The dual-layer multiple tuned mass dampers （DMTMD） and the multiple dual tuned mass dampers （MDTMD） are proposed in the present paper. Employing the goal function defined for the optimum searching, an evaluation is made for the DMTMD and MDTMD with the simplest manufacturing. The numerical results indicate that DMTMD and MDTMD provide better effectiveness and robustness than the arbitrary integer based multiple tuned mass dampers （AI-MTMD） recently proposed by the writer and odd number based multiple tuned mass dampers （ON-MTMD） with equal total mass. The DMTMD provides better effectiveness than the MDTMD, whereas the MDTMD renders higher robustness than the DMTMD. The MDTMD has larger stroke than the DMTMD. The smaller mass block in the DMTMD is larger than that of the mass block in the AI-MTMD and ON-MTMD.
