| 摘 要： | 根据力学模型提出了增大混合磁铁磁轭高度以提高承载力的方法,从承载能力、可控性及永磁工作点3个角度展开对混合磁铁结构参数的优化分析。理论分析及仿真结果表明,适当增大永磁截面积在满足系统承载力要求的同时能提高磁铁可控性;合理选取永久磁铁的截面积和厚度参数能保证磁铁工作在最大能积点。

| Abstract: | By analyzing of mechanical model, the paper advanced a method of increasing the height of magnet yoke, which can enhance the suspension force. Structure parameters of hybrid magnet were optimal designed from three angles. They are suspension force, controllability and working point of permanent magnet. The result of theoretical analysis and simulation show that increasing the cross section of permanent magnet can not only meet the command of system suspension force but also enhance controllability, and selecting reasonable parameter of the cross section and height of the permanent magnet can guarantee the maximum energy point of the magnet. |
