摘要
自1972年J.T.P.Yao(姚治平)提出土木工程界的结构振动控制以来,结构保护系统受到了广大研究者的普遍关注.这种保护系统可以用来降低自然灾害对土木工程建筑的损害.由于磁流变阻尼器结构简单、动态范围大、能耗低、出力大、鲁棒性良好,能够满足不同工程项目需求的同时还提供有效的结构抗震抗风手段,目前它是一种非常有前途的半主动结构减震装置.本文首先介绍了磁流变液和阻尼器的特性和优点,然后详细介绍了磁流变阻尼器的Bingham模型以及Simulink的强大功能,并在Simulink中进行Bingham模型的仿真分析,得出一些有益结论.
There has been a great deal of interest in use of structural proactive systems to mitigate the effects of dynamic environment hazards such as earthquakes and strong winds on civil engineering structures since 1972.One of the most promising new devices for structural vibration is magnetorheological(MR) dampers.Because of their mechanical simplicity,high dynamic range,low power requirements,large force capacity and robustness,these devices have been shown to mesh well with application demands and constraints to offer an attractive means of protecting civil infrastructure systems against severe earthquake and wind loading.In this paper,following an overview of the essential features and advantages of MR materials and devices,the Bingham model for MR damper and the advantages of Simulink are introduced in detail.Then Simulink analysis about Bingham model is made.At last,comes to some useful conclusions.
