摘要:
为了研究多级线圈磁流变阻尼器内部的磁场分布,对多级线圈磁流变阻尼器的磁路进行了理论分析,根据磁路欧姆定律给出了多级线圈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了多级线圈磁流变阻尼器的有限元模型,计算了不同磁场下各阻尼间隙处的磁感应强度.通过引入高斯函数和指数函数,模拟了磁场的分布规律以及电流对磁场的影响规律,建立了多级线圈磁流变阻尼器磁场分布的计算模型,并给出了相应计算公式.结果表明,该模型可以快速有效地计算出不同磁场下阻尼器各有效阻尼间隙处的磁感应强度,模型计算结果与有限元仿真结果吻合良好.所提模型为多级线圈磁流变阻尼器阻尼力计算以及线圈通电优化分析提供了基础.
Abstract:
In order to study the magnetic field distribution of a multi-coil magnetorheological damper, the magnetic circuit of the multi-coil magnetorheological damper is theoretically analyzed, and the computational method for the magnetic induction intensity in the effective damping gaps of the multi-coil magnetorheological damper is proposed based on the magnetic circuit Ohm’s law. The finite element model for the multi-coil magnetorheological damper is established by using the general finite element software, and the magnetic induction intensities of the effective damping gaps in different magnetic fields are calculated. The computational model for the magnetic field distribution of the multi-coil magnetorheological damper is established by using the Gaussian function and the exponential function to simulate the magnetic field distribution law and the influence of the current on the magnetic field, and the corresponding computational formulas are also given. The results show that the magnetic induction intensities of the damping gaps can be calculated effectively and quickly by using the proposed model in different magnetic fields, and the calculation results by the proposed model agree well with the simulation results by the finite element model. The proposed model lays a foundation for the damping force calculation and the optimal analysis of current inputting.
