摘要
磁流变阻尼器(Magnetorheological Damper,MRD)是一种在半主动振动控制系统中广泛应用的智能装置,建立精确的力学模型是实现精确控制的关键。综述了目前MRD的各种参数化模型,分析了各类模型的优缺点,讨论了MRD建模中还未解决的问题,磁流变液的微观机制和行为不明确,指出神经网络为代表的非参数化模型具有更好的性能。
Magnetorheological damper(MRD)is a kind of intelligent device widely used in semi-active vibration control system.Establishing accurate mechanical model is the key to achieve accurate control.Various parametric models of MRD are reviewed.The advantages and disadvantages of these models are analyzed.The unsolved problems in MRD modeling are discussed.The microscopic mechanism and behavior of MRD are not clear.It is pointed out that the nonparametric model represented by neural network has better performance.
