The design of magnetorheological fluid damper and its viscosity-temperature properties research
Abstract: Magnetorheological(MR) fluid is a kind of new smart materials，which has been paid more attention in the field of vibration reduction and vibration control for the structures in aeronautical，mechanical and civil engineering．MR damper is the damper with simple structure，small volume，low energy requirement，large damping force capacity and high ajustable range of damping force，which is the ideal measurement for semi—active control of civil engineering structures.In this paper，based on the feature of MR fluid and design principle of magnetic circuit，a model of shear and valve type MR damper with two-way pusher—over bar and 1-stage coils is designed and manufactured at first，and the basic principle for parameter selection and some problems to be noted in the process of designing and manufacturing of the MR damper are discussed．The magnetic field of the MR damper is simulated by Ansys，and the results indicate that the structure of the damper is reasonable and the magnetic field is stable and reaches the designed value．According to the demand of experiment，a set of performance test system for damper was built and debugged, the debugging results indicate that the test system is solid and reliable. Then, with the designed test system, the viscosity-temperature studies for the damper were conducted, the results show that the temperature had a great influence on the damping force produced by the designed damper at the temperature range of 0~40℃. Finally，based on the results of the performance experiment，the essential influence factors of damping force were demenstrated．Through the study in this paper，the significant influence on damping force exerted by work temperature is proved and the viscosity of MRF have less to do with the work temperature．
