为了获得低速磁浮车辆导向设计的基本参数和设计原则,开展了磁铁模块导向性能的静态分析与动态仿真研究。对不同导向方式下磁铁模块导向力、导向刚度以及垂向和横向力耦合度的大小进行比对分析,结果表明:在被动导向方式下采用磁铁横向对中布置和在主动导向方式下采用磁铁横向错位布置可以得到良好的车辆导向性能,而且后者更优;横向位移及其速度反馈主动导向可显著增加导向力和导向刚度,极大地改善模块动态导向性能,基本实现模块垂向和横向力解耦。建议低速磁浮车辆采用磁铁横向错位布置和横向位移与速度反馈主动导向方式。
In order to obtain the basic parameters and design principles of low-speed maglev vehicle guidance design, static analysis and dynamic simulation of magnet module guidance performance are carried out. The comparison of the guiding force, the guiding stiffness and the coupling degree between the vertical and the transverse force of the magnet module under different guiding modes shows that the use of the magnet transverse alignment and the active guiding mode transverse direction The dislocation arrangement can get a good vehicle guidance performance, and the latter is better; the lateral displacement and the speed feedback active guidance can significantly increase the guiding force and the guiding stiffness, greatly improve the dynamic guiding performance of the module, and basically realize the vertical and horizontal force solutions of the module Coupling. It is suggested that the low-speed maglev vehicles adopt the transverse misalignment arrangement of magnets and the active steering mode of lateral displacement and speed feedback.
