【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]:In order to obtain the magnetic induction intensity at the damping gap of Mr damper, the magnetic circuit of Mr damper is theoretically analyzed. Based on the theory of equivalent magnetic circuit, the calculation method of magnetic induction intensity at the effective clearance of Mr damper is given.Based on the general finite element software, the finite element model of Mr damper with different components is established, and the magnetic induction intensity at the damping gap is calculated, and the magnetic induction intensity under the corresponding working condition is measured.Finally, the finite element model of Mr damper is established, and the magnetic induction intensity at the damping gap is calculated and compared with the simulation value of the simplified model.The results show that the simulation results with non-working magnetic circuit are in good agreement with the measured values, and the simulation results of magnetic induction intensity based on the full-component model are more accurate.Therefore, the magnetic circuit analysis and design with finite element method should fully consider the effect of all the magnetic conductivity components in the magneto-rheological damper on the magnetic field intensity.
