The design method

effectiveness and robustness of double tuned mass damper（DTMD）have not been fully researched due to its lots of parameters.In view of this

the method for design of the DTMD was researched

the displacement response amplification factor of DTMDsingle degree of freedom system was derived.Based on min.（max.DDMF）optimized objective function

the regularity of influence of damper′s parameters on effectiveness of controlling displacement response amplification coefficient of the structure was analyzed systematically.Based on this

a simplified design method for DTMD was presented

and its effectiveness was evaluated through simulation analysis.Results show that the simplified design method proposed based on parametric research of controlled structure-DTMD system may provide a theoretical guide for practical application of DTMD.The DTMD designed according to the simplified design method can effectively reduce the dynamic response of the main structure

and the robustness of controlling effectiveness of the MTDM is better than that of single tuned mass damper（TMD）.
