摘　　要：为了实现车辆电磁制动器电磁体表面均匀磨损和减小旋转趋势,基于制动器运行机理,提出电磁体内侧磁路开槽的非对称设计方法。理论计算并设计了非对称磁路,在此基础上,利用Maxwell3D有限元仿真软件,得到了最佳的电磁体非对称结构与参数,并将对称结构与自制非对称结构电磁体作耐久性磨损试验对比,结果表明非对称结构电磁体摩擦表面的均匀磨损性明显优于对称结构电磁体,从而提高了制动器的寿命和可靠性。Based on operation mechanism of the electromagnetic brake for vehicles, to realize the even wear of the electromagnet surface and decrease the revolving tendency, an unsymmetrical magnetic circuit design method was proposed by slotting in the inside flank of the electromagnet. Theoretical analysis and calculation gave an unsymmetrical magnetic circuit design, based on which, Maxwell3D Finite element simulations software was applied to get the optimized unsymmetrical structure and parameters. By wearing comparison test of the symmetrical and unsymmetrical electromagnet, the testing result indicates that the unsymmetrical electromagnet obviously surpasses the symmetrical structure, which could enhance the life and the security of the brake.
