【摘要】 评价了双层多重调谐质量阻尼器(DMTMD)控制策略的性能。DMTMD系统参数的可能组合可形成五种DMTMD模型,本文评价其中最易制作的一种DMTMD模型。利用定义的优化目标函数,评价了DMTMD的控制性能。数值结果表明DMTMD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。但DMTMD中小质量块的冲程大于AI-MTMD和ON-MTMD的冲程。更多还原

【Abstract】 An evaluation is made on the dual-layer multiple tuned mass dampersDMTMDproposed.The five types of DMTMD can be formed in terms of the available combinations of DMTMD system parameters among them the one that can be most simply manufactured is chosen as an example to be evaluated.Employing the goal function defined for optimum searching the parameter studies are performed to assess the control performance of the DMTMD. The results indicate that the DMTMD provides better effectiveness and robustness than the arbitrary integer based multiple tuned mass dampersAI-MTMD as well as the odd number based multiple tuned mass dampersON-MTMD with equal total mass.However the stroke of the smaller mass block in the DMTMD is larger than that of the mass block in the AI-MTMD and ON-MTMD.更多还原
