| 摘 要： | 对磁流变液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HT 100G型数字特斯拉计对自行研制的2T-M R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-M R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实测值非常接近,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.

| Abstract: | This paper presents an optimum design method of MR damper based on magnetic circuit finite element analysis.First of all,by using HT100G-teslameter,the designed MR damper 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 analyzed recurring to professional magnetic circuit analysis soft and the simulation and the test results are compared.The result indicates that the theoretical values are close to measured ones and the simulation method is reliable.Finally,the optimum design for the damper is described in virtue of the variety of the materials and structure. |
