【摘要】：永磁涡流联轴器能够在无机械接触和磨损的情况下实现转矩的传输,因此广泛适用于许多工业应用场合。该文推导了运动导体涡流问题分别在固定坐标系和运动坐标系下的尤拉表述和拉格朗日表述,证明了两种表述的统一性;基于子域分析方法,提出了一种包含永磁体阵列、气隙、导体和导体背铁四个区域在内的永磁涡流联轴器场域解析模型,对该多层场域边值问题进行了求解,并推导出一种非常简洁的傅里叶级数形式的转矩表达式;为了确保在达到转矩设计要求前提下尽可能节约永磁体材料使用量,基于所建立的永磁涡流联轴器解析模型,提出一种永磁阵列优化方法。通过算例分析,并比较三维有限元分析和实验结果,验证了文中所提出的解析模型及永磁阵列优化方案的有效性。
[Abstract]:Permanent magnet eddy current coupling can transmit torque without mechanical contact and wear, so it is widely used in many industrial applications. In this paper, the Euler expression and Lagrange expression of eddy current problem of moving conductor in fixed coordinate system and moving coordinate system are derived, and the unity of the two expressions is proved, and based on the subdomain analysis method, a permanent magnet array is proposed. The field analytical model of permanent magnet eddy current coupling, which consists of four regions of air gap, conductor and conductor back iron, is solved, and a very concise expression of torque in Fourier series form is deduced. In order to meet the requirements of torque design, a permanent magnet array optimization method is proposed based on the analytical model of permanent magnet eddy current coupling. The effectiveness of the proposed analytical model and the optimization scheme of the permanent magnet array are verified by comparing the three-dimensional finite element analysis with the experimental results.
