【 摘 要 】

Multi-winding structure is a valid method to improve the damping force in the design of magnetorheology devices. Because of the arrangements of several windings in cylinder, it can greatly improve the effective area of magnetorheology(MR) fluid to achieve much larger damping force in limited space compared to conventional MR damper. In order to further promote the dynamic range and electromagnetic efficiency of MR damper, this paper shows the design of an innovative multi-winding MR damper, which has flow passage embedded in each magnetic core. Based on this special design, the effective length of the flow passage can be dramatically increased, so as the electromagnetic efficiency of the damper. It means that the damper can produce the same damping force with less power consumption. The feasibility of the design philosophy for multi-winding MR damper with embedded flow passage was verified by the simulation results of electromagnetic field and damping force. The research results show that the proposed multi-winding MR damper has much higher dynamic range and efficiency than a conventional one.
