智能减震器在建筑结构隔震中的应用

摘要

Traditional civil engineering structure vibration control device is not able to adjust damping according to earthquake excitation size, and it responses slowly and recovers poorly. Building structural control with intelligent materials has become a frontier field of the vibration control study, as an intelligent control device, a new type of intelligent shock absorbers, magneto-rheological damper, has the advantages of simple structure, easy adjusting drive, low energy consumption, quick response, almost without delay, and large and continuously adjustable damping force.%传统的土木工程结构振动控制装置不能够根据地震激励的大小调节阻尼，反应迟缓，且恢复性差。采用智能材料的建筑结构控制已经成为振动控制研究的前沿领域，一种新型的智能减震器---磁流变阻尼器作为智能控制装置，具有构造简单、调节驱动容易、能耗性小、反应迅速、几乎没有时滞，所产生的阻尼力大而且连续可调等优点。
