摘要
在永磁轴承的设计过程中,磁环间磁力的计算是极为重要的一环,而通过建立磁环的测量模型,将复杂的物理问题转化为数学问题是在计算磁力时较为通用的方法。本文利用前人的理论建立永磁轴承的分子电流模型,并通过积分定义法求解基于该模型的磁力四重积分。为了验证积分定义法求解四重积分的正确性,本文将计算结果同利用蒙特卡洛法求解的结果以及ANSYS求解的结果进行了对比。
In the design of the permanent magnetic bearing, the calculation of the magnetic force between the magnetic rings is an important part. Transforming the complicated physical problem into a mathematical problem by establishing the mathematical model of the magnetic ring is a general method when calculating the magnetic force. In this paper,the equivalent magnetic charge model of a permanent magnet bearing is established by using the formers Molecular current method,and the quadratic integral based on this model is solved by the integral definition method. In order to verify the correctness of the quadratic integral by the integral definition method,this paper compares the results with those obtained by Monte Carlo method and ANSYS.
