摘　　要：通过对倾斜式磁悬浮地球仪的电磁铁及其球体的受力情况进行分析研究,突破了传统垂直悬浮地球仪形式并探索利用边缘效应实现单自由度控制替代五自由度磁悬浮系统。针对地球仪的电磁铁进行了结构的设计与分析。通过改变其电磁学参数、几何形状等基本设计参数的研究,获得电磁铁较为合理的结构尺寸参数;经计算研究获得了电磁铁边缘效应在此磁悬浮系统中控制自由度想法的可行性。并设计实验台为理论计算结果做进一步验证。Through analyzing and studying the electromagnet in inclined-suspended globe and the force of the globe,the traditional vertical-suspended globe is broken through by exploring in utilizing edge effect to realize the probability of suspending globe with one degree of freedom controller instead of 5 DOF magnetic suspension.Then the structure of the electromagnet is designed and analyzed.Through changing the value of electromagnetism and physical dimension,rational structural parameters of the electromagnetism is obtained.In addition,the application of the edge effect in electromagnet is discussed and the feasibility of using edge effect in controlling DOF is obtained,which results is further verified through laboratory furniture designed.
