摘　　要：针对所设计的磁流变阻尼器结构特点,应用有限元软件ANSYS提供的参数化设计语言,建立了阻尼器的1/16三维结构模型,基于磁流变液与磁芯材料具有不同的非线性磁导特性的特点,应用基于单元边法的Solid117单元建立了阻尼器的有限元模型,进行了三维静态非线性电磁场分析,在后处理器中,通过求得工作区域内平均磁场强度与磁感应强度的方法,获得了阻尼器的屈服力矩特性与漏磁系数等关键参数。Depending on the characteristics of the magnetorheologieal damper, the 1/16 3-D model of the damper was built with the ANSYS APDL. Based on different nonlinear magnetization characteristics of magnetorheological fiuid and magnetic core material the finite element model of the damper was built with the edge-based Solid117 element, and 3-D static nonlinear magnetic analysis was performed. In the general post processor, with the magnetic flux density average and magnetic field intensity average of the work area, based on above results, the magnetorheological damper ＇s properties： yield torque vs current and coefficient of magnetic dispersion were calculated.
