摘　　要：通过减震措施降低核安全壳地震加速度响应,确保强震作用下核电设备的安全,对提高核安全壳抗震韧性具有现实意义。调谐质量阻尼器(tuned mass damper,TMD)能有效地降低风振响应,用于控制地震响应,存在频带窄、减震效率低等不足。文中将TMD与惯容结合,提出采用调谐质量惯容阻尼器(tuned mass damper inerter,TMDI)降低核安全壳地震加速度。基于性能需求设计思想与H∞优化准则建立了TMDI最优参数设计方法。在此基础上,使用子结构思想联合ABAQUS与Matlab开发了数值模拟方法,实现了TMDI控制下核安全壳地震响应有限元模拟。通过对某核安全壳有限元模型进行TMDI地震控制算例分析,验证了理论分析的有效性。结果表明,采用TMDI时核安全壳顶部峰值加速度减震率为46.1%,且TMDI达到相同减震指标时所需调谐质量减少了28.2%。Reducing the seismic acceleration response of nuclear containment and ensuring the safety of nuclear power equipment under strong earthquakes is of practical significance for improving the seismic toughness of nuclear containment.Tuned mass damper(TMD)can effectively reduce the wind vibration response,but it has the disadvantages of narrow frequency band and low damping efficiency for seismic response control.By combining TMD with inertial volume,a tuned mass damper inerter(TMDI)is proposed to reduce the seismic acceleration of nuclear containment.Based on the performance requirement design idea and H∞optimization criterion,an optimal parameter design method for TMDI was established.On this basis,a numerical simulation method is developed by using the substructure idea combined with ABAQUS and Matlab,and the finite element simulation of the seismic response of nuclear containment under TMDI control is realized.The validity of the theoretical analysis is verified by the TMDI seismic control example of a finite element model of a nuclear containment.The results show that the peak acceleration absorption rate of the top of the nuclear containment is 46.1%when TMDI is used,and the tuning mass required when TMDI reaches the same damping index is reduced by 28.2%.
