磁流变液阻尼减振器力学模型及其发展
|
摘要
磁流变液是一种流变特性随施加磁场强度大小和方向而变化的粘性流体,磁流变阻尼器是一种智能型主动控制的执行装置,在汽车行业已经引起高度关注,国内外相关专家对其进行了广泛研究。本文详细综述了磁流变阻尼器动力学模型的研究现状,分析了各种模型的优缺点,讨论了目前磁流变阻尼器研究中有待解决的问题。认为有必要加强减振器结构参数、振动信号特性、负载等与所需阻尼力关系的研究,加强神经网络和模糊逻辑等现代智能控制技术在磁流变阻尼器控制方面的研究,这是解决磁流变技术工程应用问题的有效途径。
Magnet-orheological fluid is one viscidity fluid which orheological properties can be changed with the magnet strength and direction applied.Magnet-orheological damper is a kind of intelligent actuator for semi-active control,and popular attention has been aroused for its application in vehicle.It has been broadly studied in the world.This author reviewed the actual state of MRD dynamical models,analyzed their advantages and disadvantages,and discussed current problems in the research.It is argued that the study of the relation about the parameters of damper,and the characteristic of vibration signals,loads and damper force are very important,and the investigation of application of modern intelligent control methods in MRD control should be strengthened.All these are effective methods of resolving the problem of MRD application in engineering.
