Influencing of Winding Cylinder of Differential Self-induced Magnetorheological Damper on Magnetic Characteristics

In order to solve the problems that the working magnetic fields and induced magnetic fields of the differential self-induced magnetorheological damper(DSMRD) were influenced by the structure parameters of the winding cylinder,the finite element model was established.By comparing the magnetic fields and induced voltage amplitude in different kinds of materials and structure parameters of winding cylinder,the relationships among materials,structure parameters and magnetic fields were obtained.The simulation results show that the maximum values of the working magnetic field will decrease with the increasing of the thickness of the cylinder body,however,the average magnetic field in the cylinder body with magnetic material will increase.On the other hand,the induced voltage amplitude will increase with the increasing of the depth of the winding cylinder,but the maximum value of the magnetic field will decrease.Finally,the optimized DSMRD was obtained.
