【摘要】 电/磁流变液(ERF/MRF)是在电/磁场作用下,其流变学性能可迅速响应,且易于控制的新型智能材料。基于电/磁流变技术的装置包括阻尼器、制动器、离合器、抛光装置和液压阀等,都有很大的潜在发展前景,有些已在汽车、健身设备和抛光机械等工程领域取得商品化应用。本文在分析电/磁流变液装置工作模式的基础上,对近十年来电/磁流变液装置以及这些装置在机械工程领域的应用进行了分类和全面综述,对其存在的问题及应用前景进行了展望。更多还原

【Abstract】 Electrorheological fluids(ERF)/ Magnetorheological fluids(MRF) are two classes of new intelligent materials whose rheological characteristics change rapidly and can be controlled easily in the presence of an applied magnetic field. The devices based on ERF/MRF including dampers,brakes,clutches, and hydraulic valves,polishing devices,etc,have a very promising potential future, and some of them have been used commercially in engineering applications,such as automobiles, exercise equipment,polishing machines, etc. In this paper, the operation modes of ERF/MRF devices are analyzed firstly, then the developments in 1ast decade of ERF/MRF devices(especially dampers) and their applications in mechanical engineering are classified and reviewed comprehensively, the main problems and developing tendency are discussed finally.更多还原
