| 摘 要： | 基于N iTi形状记忆合金(SMA)丝和成品粘滞阻尼器设计研制了一种新型SMA-粘滞阻尼器,并将其应用于一大跨度斜拉桥的振动控制;建立了SMA粘滞阻尼器—大跨度斜拉桥的动力有限元计算模型,计算结果表明:和普通粘滞阻尼器相比,文章所设计的SMA-粘滞阻尼器的耗能减振效果更为明显,能有效地降低大跨度斜拉桥桥塔和主梁在简谐振动和地震作用下的位移幅值.

| Abstract: | Based on NiTi shape memory alloy threads and ordinary fluid viscous damper,a kind of new-type SMA-viscous damper has been designed and developed,which has been used to control the vibration of long-span cable stayed bridge.The dynamic finite element model of long span stayed bridge with SMA-viscous damper is established,and the calculation results show that the effect of energy dissipation and vibration reduction of SMA-viscous damper is more distinct than the ordinary viscous damper.The SMA-viscous damper ... |
