摘要：
To meet the requirements of vibration and noise reduction in hydraulic pipeline, a design method of double-outlet shear-valve magnetorheological(MR) damper was proposed. Based on the Bingham model of MR damper, combining the structural design of the MR damper with the design of the magnetic circuit, the calculation formula of the structural parameters of the damper was deduced. A finite element analysis software COMSOL was selected to simulate the electromagnetic field. An accurate and simple computational method based on the simulation model was established to calculate the viscous stress and shear stress under different control current. According to the proposed design method, a prototype of MR damper was developed, and the dynamic mechanical properties of prototype were tested. The test results show that the performance parameters of the MR damper are basically identical with the theoretical design values, which proves the correctness and feasibility of this design method, and the design method can simplify the design process and reduce the volume of MR damper. © 2019, Editorial Department of Transaction of Beijing Institute of Technology.
