摘　　要：利用惯质单元和电磁阻尼单元代替传统调谐质量阻尼器的质量和黏性阻尼,形成电磁调谐惯质阻尼器(Electromagnetic Tuned Inerter Damper,ETID),以单自由结构为研究对象,对ETID的减振性能进行理论与数值计算。首先,建立单自由度-ETID耦合结构动力学方程,以被控主结构的位移峰值为优化目标,利用H∞范数优化理论进行参数优化,通过蒙特卡洛模式搜索法和粒子群算法两种智能算法对ETID的频率比、电磁阻尼比和机电耦合系数进行数值优化。其次,在不同失谐频率下开展调谐参数的频域分析,研究ETID的鲁棒性。最后,在惯质比为2%的条件下,进行多个地震波激励下的时域仿真分析,并与经典调谐质量阻尼器(Tuned Inerter mass damper,TMD)的减振性能进行对比,仿真结果表明在特定的地震作用下ETID控制效果明显,鲁棒性能良好。The inertial elements and electromagnetic damping elements are used to replace the mass and viscous damping of the traditional tuned mass dampers,and an electromagnetic tuned inertial damper(ETID)is formed.The vibration mitigation performance of the ETID coupled with a single-DOF structure is calculated theoretically and numerically.Then,the frequency domain analysis of the tuning parameters is carried out at different detuning frequencies to study the robustness of the ETID.Finally,the time domain simulation of multiple seismic wave excitations is carried out under the condition of 2%inerter ratio,and the vibration mitigation performance of ETID is compared with that of classical Tuned Mass Damper(TMD).The results show that the ETID is robust and effective under the action of specific seismic load.
