摘　　要：针对直线电机式电磁主动悬架推力波动大、推力密度低的问题,提出一种非均匀齿结构的Halbach圆筒型永磁直线电机。利用解析法对该电机的边端力模型进行推导,并进一步分析非均匀边端齿结构对电机输出性能的影响。根据分析结果选取边端齿的轴向长度和径向削短高度、永磁体高度和径向充磁的长度、内部齿的长度5个参数作为优化因子,以电机输出推力最大和推力波动最小为优化目标进行田口法和响应面法优化,得到参数的最优值。试制了原理样机并搭建了实验平台,对电机进行空载与负载实验,验证了所提结构及其设计优化方法的有效性。A Halbach tubular permanent magnet linear motor with a non-uniform teeth structure is proposed in this study to solve the problems of high ripple and low force density of a linear electromagnetic active suspension system. The end force model is derived using the analytical method, and the effects of non-uniform teeth structure on the output performance of the motor are analyzed. Based on the analysis results, five parameters, including the axial length and radial cut length of the end teeth, thickness and radial-magnetization length of the permanent magnet, and length of the inner teeth, are selected as optimization factors. Taguchi and response surface methods are adopted to optimize the maximum output force and minimum ripple of force simultaneously, and the optimal parameters are obtained. Finally, a prototype is manufactured and an experimental platform is set up to carry out the no-load and load experiments to verify the effectiveness of the proposed structure and its optimization methods.
