提出了基于刚度连接的双层调谐质量阻尼器（SDTMD）装置。SDTMD是在双层调谐质量阻尼器（DTMD）的基础上，在主体结构与小质量块之间设置一个附加弹簧而构成。经定义SDTMD最优参数的评价准则，在频域内研究了质量比对SDTMD控制结构位移响应时最优参数和有效性以及冲程的影响；并与TMD、DTMD和基于阻尼连接双层调谐质量阻尼器（DDTMD）装置进行了比较。数值结果表明，SDTMD的控制有效性明显高于TMD、DTMD和DDTMD。%Stiffness-connection-based double-tuned-mass dampers(SDTMD)were proposed here.Specifically,an added stiffness between the controlled structure and the smaller mass block in a DTMD was introduced to form a SDTMD. In order to obtain optimal parameters of SDTMD,an optimal criterion was defined.Employing this defined criterion,the influences of mass ratio on optimal parameters,effectiveness and stroke of SDTMD were studied numerically in frequency domain.Furthermore,the optimal performances of SDTMD were compared with those of TMD,DTMD,and damping-connection-based double-tuned-mass dampers(DDTMD).The numerical results showed that the effectiveness of SDTMD is remarkably higher than those of TMD,DTMD and DDTMD.
