| 標(biāo)題 |
| 杭州灣跨海大橋北航道橋斜拉索減振研究(31 卷) |
| 英文標(biāo)題 |
| Study on the Vibration Reduction of the StayedCable on the Northern Waterway Bridge of Hangzhou Bay Bridge |
| 摘要 |
| 運(yùn)用福斯(Foss)迭代法求解設(shè)置黏性剪切阻尼器（VSD）減振拉索的振動(dòng)方程，得到復(fù)特征值和對(duì)數(shù)衰減率。以對(duì)數(shù)衰減率大于等于003為目標(biāo)函數(shù)，對(duì)杭州灣跨海大橋北航道橋斜拉索減振用VSD進(jìn)行優(yōu)化設(shè)計(jì)，并對(duì)安裝VSD的減振效果進(jìn)行分析。結(jié)果表明：減振拉索的每階模態(tài)均有對(duì)應(yīng)的VSD |
