Research on Thermal Structure Field of Magnetorheological Device Under Multiple Working Condition by Song Chen, Jing Yang, Jin Huang

“…The shear stress,the thermal magnetization,the viscosity and the rheological properties of the magnetorheological fluid are significantly reduced under high temperature,and the damage of the thermal stress produced by the high temperature to the chain structure of the magnetorheological fluid seriously affected the transmission performance of the magnetorheological transmission.Based on the nonlinear relationship between shear modulus and magnetic field strength,the elastic modulus of magnetorheological fluid under the action of magnetic field is calculated.The temperature,thermal deformation and the distribution law of the equivalent thermal stress in the magnetorheological fluid gap are studied under the condition of the slip and the power loss of the excitation coil and the influence of the slip power,current,gap width and the winding series of the excitation coil on it is discussed.The results show that both the slip power and the excitation coil current will cause a significant increase in the temperature of the magnetorheological fluid,and the resulting thermal deformation has little influence on the structure,and the equivalent thermal stress is greatly affected.There are obvious differences in the equivalent thermal stress distribution between the working gap and the no working gap of MRF.The performance of magnetorheological transmission device can be improved by changing the width of the gap and the series of windings under the condition of constant slip and current.…”
