双调谐质量阻尼器参数较多,迄今其设计方法、有效性和鲁棒性的研究仍不完善。针对双调谐质量阻尼器的设计方法进行了研究,推导了双调谐质量阻尼器-单自由度结构体系的位移响应放大系数,基于min.(max.DDMF)最优化目标函数,系统地分析了阻尼器参数对受控结构位移响应放大系数控制效果的影响规律;在此基础上,给出了一种双调谐质量阻尼器(DTMD)的简化设计方法,并通过仿真分析对该简化设计方法的有效性进行了评价。结果表明,基于受控结构-DTMD系统参数研究提出的简化设计方法可为DTMD的实际应用提供理论指导;依据简化设计方法设计的双调谐质量阻尼器可有效降低受控结构的动力响应,且控制效果的鲁棒性明显优于单调谐质量阻尼器(TMD)。
The double tuned mass damper has many parameters, so far the research on its design method, validity and robustness is still not perfect. Aiming at the design method of double tuned mass damper, the displacement response amplification factor of double tuned mass damper - single degree of freedom structure system is deduced. Based on min. (Max.DDMF) optimization objective function, The effect of the parameters of the controller on the control effect of the amplification coefficient of the displacement response of the controlled structure is discussed. Based on this, a simplified design method of a dual tuned mass damper (DTMD) is given. The simplified design method is validated by simulation Sex was evaluated. The results show that the simplified design method based on controlled structure-DTMD system parameters can provide theoretical guidance for the practical application of DTMD. The double tuned mass damper designed according to the simplified design method can effectively reduce the dynamic response of the controlled structure and control The robustness of the effect is significantly better than the single tuned mass damper (TMD).
