摘　　要：该文提出黏滞阻尼与滞变阻尼共同作用的双阻尼模型调谐质量阻尼器(Dual Damping Tuned Mass Damper,DD-TMD),并对白噪声作用下DD-TMD进行减震优化研究。讨论了DD-TMD的构成、优势和应用范围,并总结了DD-TMD的力学机理。提出适用于DD-TMD的H_(2)优化方法,并通过数值寻优得到了最优参数和基于稳定区域的DD-TMD参数优化方法。此外,通过DD-TMD的H_(2)优化方法进一步得到了DD-TMD的等效附加黏滞阻尼比,为工程设计奠定应用基础。以变摩擦摆式调谐质量阻尼器(Variable Friction Pendulum Tuned Mass Damper,VFP-TMD)为DD-TMD的实际应用算例,通过20条地震波检验所提出的优化方法对地震激励的减震性能影响。结果表明:H_(2)优化下的DD-TMD可以提供与常规黏滞阻尼TMD相当的控制效果。采用DD-TMD可以通过随机理论成功模拟与常摩擦阻尼等效的黏滞阻尼,并为带有初始摩擦的VFP-TMD提供有效可靠的优化设计方法。相较于前人所做的数值寻优方法,按照DD-TMD模型优化的VFP-TMD可以提供更加优异的减震控制效果且阻尼耗能能力提高了16.6%。This study presents the seismic mitigation investigation subjected to white-noise excitation for Dual Damping Tuned Mass Damper(DD-TMD)that combines viscous damping with hysteretic damping.To begin with,the configuration,advantages,and applications of DD-TMD are introduced,and the mechanism for DD-TMD is summarized.H_(2) optimization for DD-TMD is proposed to obtain the optimal parameters through the algebraic solution,and the design process for DD-TMD is carried out.In addition,the effective additional viscous damping of the DD-TMD is further illustrated upon the H_(2) optimization for DD-TMD,which lay an application foundation for pertinent engineering design.As a real application of DD-TMD,Variable Friction Pendulum Tuned Mass Damper(VFP-TMD)was applied as an illustration of DD-TMD to verify the effectiveness of the proposed methods for vibration control subjected to 20 sets of earthquake records.Results indicated that DD-TMD with H_(2) optimization provided a comparative advantage on seismic mitigation capacity toward conventional viscous damping TMD.The equivalent viscous damping had successfully performed the constant friction damping by stochastic linearization method,indicating that H_(2) optimization based on DD-TMD provided a reliable and functional design process for the VFP-TMD with inevitable initial friction coefficient.Compared with the former study on VFP-TMD by numerical searching method,the proposed DD-TMD design process with H_(2) optimization performes better on seismic control performance and improved 16.6%of damping energy dissipation capacity.
