本文总结了为提高对调谐质量阻尼器（TMD）一些重要特性的认识而进行的参数化研究的结果。利用稳态谐波激励分析和时程分析，研究了失谐对TMD部分参数性能的影响。埃尔森特罗和墨西哥激励用于时程分析。研究了调谐准则的影响和数值调谐的意义。绘制了单自由度结构的TMD设计与多自由度结构的某一模态之间的对应关系，将TMD设计简化为控制多模态结构的单一模态。给出了一个实例来说明设计过程。研究了用多调谐质量阻尼器控制多结构模态的方法。
This paper summarizes the results of a parametric study performed to enhance the understanding of some important characteristics of tuned mass dampers (TMD). The effect of detuning on some of the TMD parameters on the performance is studied using steady-state harmonic excitation analysis and time-history analysis. The El Centro and Mexico excitations are used for time-history analysis. The effects of tuning criteria and significance of numerical tuning are also studied. The correspondence between the design of a TMD for a SDOF structure and a certain mode of a MDOF structure is drawn to simplify TMD design to control a single mode of a multimodal structure. An example is given to illustrate the design procedure. Investigations are made regarding controlling multiple structural modes using multi-tuned mass dampers (MTMD).
