摘要:
为得到磁流变阻尼器阻尼间隙处的磁感应强度,对磁流变阻尼器的全构件磁路进行了理论分析,根据等效磁路理论给出磁流变阻尼器有效间隙处磁感应强度的计算方法.基于通用有限元软件建立包含不同构件的磁流变阻尼器有限元模型,计算阻尼间隙处的磁感应强度,并对相应工况下的磁感应强度进行实测.最后,建立了磁流变阻尼器的全构件有限元模型,计算了阻尼间隙处的磁感应强度,并与简化模型的仿真值进行对比. 结果表明,考虑非工作磁路的仿真计算结果与实测值基本吻合,基于全构件模型的磁感应强度仿真计算结果更加准确.因此在利用有限元进行磁路分析和设计时,应充分考虑磁流变阻尼器中所有导磁构件对磁场强度的影响.
Abstract:
To obtain the magnetic induction intensity of the damping gap in a magnetorheological(MR)damper, the magnetic circuit of a MR damper based on a full component model is theoretically analyzed, and the computational method for the magnetic induction intensity of the effective damping gaps of the MR damper is proposed based on the equivalent magnetic circuit theory.The finite element models for the MR damper with different components are established by using the general finite element software. The magnetic induction intensities of the effective damping gaps are calculated,and the magnetic induction intensities under the corresponding working conditions are tested. Finally, a full component finite element model for the MR damper is built to obtain the magnetic induction intensity of the damping gap, and the simulation results are compared with those of the simplified model. The results show that the simulation results of the models considering the non-working magnetic circuit are in good agreement with the experimental values, and the results of magnetic induction calculation based on the full component finite element model are more accurate. Thus, the influence of all of the magnetic conductors in the non-working magnetic circuit on the magnetic induction intensity of the damping gap should be considered during the analysis and the design of the magnetic circuit by the finite element method.
