不同参数组合的最优多重调谐质量阻尼器
Optimum Multiple Tuned Mass Dampers Considering Available Combinations of System Parameters
摘要
Abstract
Multiple tuned mass dampers (MTMD)consist of many tuned massdampers with a uniform distribution of natural frequencies .Five types of MTMD(i,e,MTMD-1 to MTMD-5)are formed in light of available combinations of system parameters.Based on the transfer function of the general MTMD,the unified expression for the displacement dynamic magnification factor(DDMF)is derived for MTMD-1 to MTMD-5.Utilizing a numerical optimum researching technique,a study is performed to investigate the optimum parameters,including:frequency spacing,damping ratio,tuned frequency ratio and total number.It is demonstrated that it is preferable to select the MTMD-1 for engineering applications.关键词
