Performance Test of Nonlinear Tuned Mass Damper Vibration-absorbing Device for a Slender Structure under Wind-induced Vibration
摘要
Abstract
The fatigue failure accidents of slender structures such as petrochemical towers and chimneys under wind-induced vibration occurred frequently.Structure vibration control using nonlinear tuned mass damper (TMD)can be used.In order to study the performance of such nonlinear TMD,a test model of nonlinear TMD device to control the slender structures under wind-induced vibration is designed and the experimental study is conducted.The performances of the TMD device are contrasted on two conditions in-cluding different excitation size and initial amount of preload of wire rope isolator.The results show that the performance of the TMD device with wire rope isolator is very good,and the amplitude is reduced by about 85%in the resonance region of main system.Performances of the TMD are good under different ini-tial compressive preloads,while they decrease quickly under initial tensile preloads.When isolators are in the allowable range of compression,the greater the excitation is,the better the performance is.关键词
