| Abstract: | A novel magnetorheological(MR) fluid and MRF damper with a spring accumulator were prepared.The magnetic properties of carbonyl iron particles were characterized by VSM;the apparent viscosities and the magnetic field-induced shear stresses of the magnetorheological fluids above were investigated by an advanced rheometric expansion system;the properties of MR damper were tested by an electro-hydralic servocontrol testing system.The results show that carbonyl iron particle chosen has excellent magnetic property;the stability of MR fluid was improved;the force of the MR damper under the current of 2A is about 15kN. |
