摘要

永磁电动悬浮系统在高速情况下具有自稳定的特点，并且安装维护简单，在超高速管道磁浮运载中具有重要的应用价值。文章以超高速永磁电动悬浮系统为对象，对“Halbach永磁阵列-导体板”结构进行系统建模，提出了一种横向端部断面边界条件的构建方法，明确了电磁力的求解方法。同时，对电磁力特性开展研究，分析了电磁力随电磁参数、结构参数变化的规律。利用转盘试验平台开展了原理性验证试验，通过有限元仿真和试验结果对比，说明了所建电磁力模型的正确性。

Abstract

The permanent magnet electrodynamic levitation system has been proven significantly valued for applications in ultra-high-speed tube magnetic levitation transport

due to its self-stabilizing performance at high speeds and easy installation and maintenance. This paper focused on the ultra-high-speed permanent magnet electrodynamic levitation system and presented a method for constructing boundary conditions for transverse end sections

by modeling the "Halbach permanent magnet array—conductor plate" structure. Additionally

a method to solve the electromagnetic force was proposed. By analyzing the change rules of electromagnetic force with electromagnetic parameters and structural parameters

this paper revealed the characteristics of electromagnetic force. The principle of the electromagnetic force model was validated through a comparison between the finite element simulation results and findings from a verification experiment carried out on a rotary experimental platform.
