直线型Halbach磁体和导体板构成的电动式悬浮系统的实验装置设计

Experimental facility design of EDS maglev with linear Halbach PM and conducting sheet

永磁和导体板构成的电动式悬浮系统由导体板和直线型Halbach永久磁体构成,悬浮力和磁阻力是导体板上产生的涡流和磁体的相互作用的结果.研究了实验装置的结构,包括磁体和直流电机,测试、分解电磁力为悬浮力和磁阻力的机构,最后制造实验装置.实验和仿真的对比,说明力的解耦是成功的.这是永久磁体导体板悬浮系统工程化的第一步.

The EDS maglev is made up of conducting sheet and linear PM halbach arrays, in which the lift and drag forces of EDS system result from the interaction between eddy-current of conducting sheet and PM magnetic fields. The content of this paper includes： the structure of experimental facility, including magnet and DC motor; the creation of the decouple mechanism to measure lift and drag forces; finally the manufacture of this facility. By contrasting the experiment and simulation, the conclusion is drawn that forces are successfully decoupled, which is the first step of EDS maglev project with PM and conducting sheet.
