摘要
针对磁流变液(Magneto-Rheological,MR)阻尼器提出了基于磁路有限元分析的优化设计方法。首先运用HT100G型数字特斯拉计对研制的2T-MR阻尼器进行现场磁感应强度实测,获取了不同电流工况下阻尼器内外筒间隙处的磁感应强度实测值。然后,运用专业磁场分析软件对2T-MR阻尼器的工作磁路进行了有限元分析,并将试验结果与仿真结果进行了比较。分析结果表明,有限元方法的计算值与试验实测值非常接近,从而验证了仿真方法的可靠性。最后,运用该仿真方法对不同材料、不同结构参数的阻尼器进行了优化设计。
An optimum design method of MR damper is presented based on magnetic circuit finite element analysis.First of all,the designed MR damper using of HT100G-teslameter is tested when exposed to different currents and the magnetic induction intensity of the clearance is gained.Secondly,the finite element model of the magnetic circuit is established and analyzed using professional magnetic circuit analysis software.The simulation and test results are compared subsequently.The result indicates that the theoretical values matched measured ones very well and the simulation method is reliable.Finally,the optimum design of the MR damper is also made in virtue of the variety of its material and structure.
