摘要
为研究高温超导磁悬浮列车的静态悬浮特性并揭示超导磁力与关键设计参数的关系,给出了一种基于临界态Bean模型的超导磁力有限元计算方法,在此基础上研究了超导磁力的静态特性,并设计了超导磁力测试试验对理论分析进行了验证。研究得出超导磁力具有明显的磁滞特性,当超导体与永磁体半径比为1时超导磁力有最大值,超导磁力在一定范围内随永磁体或超导体厚度的增加而增加,超导磁力随永磁体相对磁导率及超导体临界电流密度的增加而增加,超导体与永磁体发生径向偏移时会产生径向回复力。
In order to study the static suspension characteristics of high temperature superconducting maglev train and reveal the relationship between superconducting magnetic force and key design parameters,a finite element method of superconducting magnetic force based on critical Bean model was presented.On this basis,the static characteristics of the superconducting magnetic force were studied,and the superconducting magnetic force test was designed to verify the theoretical analysis.The results show that the superconducting magnetic force has obvious hysteretic characteristics.When the radius ratio of superconductor to permanent magnet is 1,the superconducting magnetic force has the maximum value.The superconducting magnetic force increases with the thickness of permanent magnet or superconductor in a certain range.The superconducting magnetic force increases with the relative permeability of permanent magnet and the critical current density of superconductor.Radial restoring force will be produced when the body and permanent magnet are radically offset.
