The armature is an important part affecting the energy conversion efficiency of a reluctance accelerator. In this paper, six kinds of soft magnetic materials are chosen and four structures are designed for the armature. At first, the circuit and magnetic force are theoretically analyzed. Then the armatures with different materials and structures are used in the simulation, and the performances are compared and analyzed. At last, the experiment verifies the theory analysis and simulation design. It is concluded that the saturation flux density and conductivity of the material are the key factors affecting the armature force, and the optimization of armature structure can effectively restrain the eddy current, reduce negative force and improve efficiency. Compared with cutting slits in solid armatures, laminating the sheets radially can reduce the eddy current more efficiently. Although slitting can prevent the eddy current to a certain extent, meanwhile, it will decrease the magnetic force because of the losing of magnetized volume and the surface area. Hence, choosing the high saturation flux density material and making out the armature with radially_laminated sheets will improve the efficiency of the reluctance accelerator. In this paper, the silicon steel radially_laminated armature is a better choice for the armature design of the reluctance accelerator.

电枢是影响磁阻加速器能量转换效率的重要部件。本文选用六种软磁材料，设计了四种结构的电枢。首先从理论上分析电路和磁力。然后使用不同材料和结构的电枢进行仿真，并对性能进行比较分析。最后通过实验验证了理论分析和仿真设计。得出材料的饱和磁通密度和电导率是影响电枢力的关键因素，电枢结构的优化可以有效抑制涡流，降低负向力，提高效率。与实心电枢中的切缝相比，径向层压薄片可以更有效地减少涡流。纵切虽然可以在一定程度上阻止涡流，但同时会因磁化体积和表面积的损失而降低磁力。因此，选择高饱和磁通密度材料和径向叠片制作衔铁将提高磁阻加速器的效率。在本文中，硅钢径向叠片电枢是磁阻加速器电枢设计的较好选择。选择高饱和磁通密度材料并用径向层压片制作衔铁将提高磁阻加速器的效率。在本文中，硅钢径向叠片电枢是磁阻加速器电枢设计的较好选择。选择高饱和磁通密度材料并用径向层压片制作衔铁将提高磁阻加速器的效率。在本文中，硅钢径向叠片电枢是磁阻加速器电枢设计的较好选择。
