三峡大坝升船机是三峡水利枢纽工程中重要的通航设施之一。就其通航规模、提升重量及高度而言，均属国内外已建、在建升船机之首位。本文以该大型升船机为工程背景，对升船机顶部厂房地震鞭梢效应问题提出了磁流变智能自适应减震控制的原理、设计方法和效果分析。 - The experimental results on seismic simulator verify that the mr damper in the passive off mode provided the information on the minimum effectiveness of the damper if the external power was cut off , in which the seismic responsesof the tall building and podiun structure were reduced . when the mr damper worked in the six kinds of semi - active logic control methods , the seismic responses of the two building were further reduced compared with those when the mr damper worked in the passive off mode
地震模拟振动台试验结果表明： mr阻尼器的passiveoff方式是外部电源被切断时的最低控制效果，能消除原结构地震反应的鞭梢效应，并使主楼和裙房的地震反应有一定的减少，六种半主动逻辑控制方法的减振效果比passiveoff方式更好，多mr阻尼器控制的效果优于单mr阻尼器。
