摘要
随着科技的发展,人们对于磁悬浮技术的关注度不断提高,源于磁悬浮能够实现物体间的不接触从而能够大大减少摩擦力。针对磁悬浮系统本身的具有不稳定的特点,本设计在对磁悬浮特性及工作原理充分分析的基础上,采用磁性仿真软件Maxwell对永磁体及线圈相关磁性元件进行仿真以及力学分析,构建了力学、电磁学的非线性化模型,设计相关的硬件电路,完成实物的调试。通过试验,实现了悬浮磁铁质量块(26~35g)的悬浮控制,悬浮高度距大环形磁铁上表面27~47mm,悬浮稳定可靠,稳态误差小于0.1mm。
With the development of science and technology,people pay more attention to the magnetic levitation technology,because the magnetic levitation can realize the non contact between objects so that the friction can be greatly reduced.The unstable characteristics of the magnetic levitation system itself have become the difficulty of the magnetic levitation control technology.On the basis of the analysis of the magnetic levitation characteristics and the working principle,the magnetic simulation software Maxwell is used to simulate and analyze the magnetic components of the permanent magnet and the coil,and the non line of the mechanics and electromagnetics is constructed.The related hardware circuit is designed and the hardware circuit is designed.The levitation control of the magnet mass block(26~35g)is realized.The levitation height is 27~47mm on the upper surface of the large ring magnet,and the levitation is stable and reliable,and the steady-state error is less than 0.1mm.
