摘　　要：针对调谐质量阻尼器(Tuned Mass Damper,TMD)通常需要较大的附加质量,安装空间受限以及质量块运动时需要较大的行程等问题,基于平动‐转动运动形式相互转化和能量守恒原理,本文提出了利用转动惯量虚拟平动惯性质量的TMD控制系统(Rotary inertia virtualizing translational mass based Tuned Mass Damper,简称RTMD),进行RTMD控制系统的设计概念,以单自由度结构对象为例建立了附加RTMD控制系统的运动方程,分析了RTMD控制系统参数对结构振动控制效果的影响规律。结果表明控制效果与系统的质量比、惯质比、阻尼比等参数密切相关,相关规律也可以推广到一般多自由度结构体系一阶振动的调谐吸振减振控制。进行了模型振动台试验研究,时域分析和频域分析结果均表明,试验结果与基于理论模型的数值分析结果一致性良好,验证了RTMD控制系统理论模型的正确性、设计参数的合理性以及控制系统应用于实际问题的可行性。The traditional Tuned Mass Damper(TMD)has many issues,such as large additional mass requirement,limited installation space restrictions and large motion stroke required when the mass block vibrates.Based on the principle of translation-rotation mutual transformation and conservation of kinetic energy,the rotary inertia virtualizing translational mass based Tuned Mass Damper(RTMD)is proposed in this paper.The conceptual design of RTMD control system is carried out,and the motion equation of RTMD control system is established with the reference of a single degree of freedom system.The influence law of RTMD control system parameters on the vibration control effect of structure is analyzed.It is discovered that the control effect is closely related to the system’s physical mass ratio,inertial mass ratio,damping ratio,and such regulations can be applicable to general multiple degrees of freedom systems.The correctness of the design parameters of the RTMD control system and the realizability of the control system are verified by shaking table test of the design model.The results of time domain analysis and frequency domain analysis show that the dynamic response obtained from shaking table test is consistent with the dynamic response of numerical simulation,which verifies the correctness of the established theoretical equations of RTMD control system.
