摘要: 磁流变阻尼器作为优秀的半主动控制器件,已被广泛运用于各种场合的振动控制。目前磁流变阻尼器的设计方法在很大程度上仍然依赖于设计者的经验,无法对其进行精确的计算。从磁流变液的本构关系和磁流变阻尼器的阻尼力模型出发,着重论述磁流变阻尼器的构造与磁路的设计方法,并运用有限元对磁路部分进行仿真分析;通过参数优化设计出经济合理的磁流变阻尼器,用MATLAB对其进行性能分析,所论述的设计方法能满足工程精度要求,尤其对土木结构工程中磁流变阻尼器的设计具有指导意义。Abstract: Magnetorheological (MR) damper is one of the most excellent new devices for sem-i active control. The research on design of MR dampers should be improved to accelerate the application of MR dampers. In this paper, after a review of the features and models of MR materials and devices, geometrical design and magnetic circuit design of MR dampers are presented and discussed in detail, then an example is provided. The theory can provide a guidance for the design of MR dampers applied in civil engineering.
