摘要

为了提高轴向式电涡流阻尼器的阻尼性能，引入Halbach永磁阵列，建立了Halbach阵列轴向式电涡流阻尼器(Halbach Array Axial Eddy Current Damper，HAECD)模型。首先阐明了HAECD的整体构造、工作原理与力学特性；采用三维电磁场有限元瞬态分析方法验证电涡流单元阻尼系数计算的准确性。然后建立四种阵列方式的电涡流阻尼单元计算模型并进行了优化分析。最后分析了永磁体厚度、磁化角度及磁极配比对HAECD阻尼系数的影响。研究结果表明：Halbach阵列相较于其他阵列方式，在同等磁体体积情况下的阻尼系数提升率最高可达59.2%；针对本装置，适当增加永磁体厚度能有效提升阻尼系数，最优磁体厚度为31mm；磁化角度为2°时阻尼系数最大；阻尼系数随着磁极配比的增大而逐渐缓慢增加，磁极配比为2.5时，阻尼性能最优。

Abstract

In order to improve the damping performance of axial eddy current damper, the model of axial eddy current damper (Halbach Array Axial Eddy Current Damper,HAECD) of Halbach array is established by introducing Halbach permanent magnet array. Firstly, the overall structure, working principle and mechanical properties of HAECD are expounded, and the three-dimensional electromagnetic field finite element transient analysis method is used to verify the accuracy of eddy current element damping coefficient calculation. Then the eddy current damping element calculation models of four array modes are established and optimized. Finally, the effects of permanent magnet thickness, magnetization angle and magnetic pole ratio on the damping coefficient of HAECD are analyzed. The results show that compared with other arrays, the damping coefficient of Halbach array can be increased by up to 59.2% under the same magnet volume. For this device, properly increasing the thickness of permanent magnet can effectively increase the damping coefficient, the optimal magnet thickness is 31mm, and the maximum damping coefficient is obtained when the magnetization angle is 2 °. The damping coefficient increases slowly with the increase of magnetic pole ratio, and the damping performance is the best when the magnetic pole ratio is 2.5.
