摘要： 针对传统磁悬浮转子动力学模型简单、模态分析误差较大的问题,提出考虑转子间接触效应的建模方法。采用接触有限元法建立磁悬浮转子过盈配合的有限元模型,通过理论计算和静力仿真分析相结合的方式,优化接触刚度因子(normal stiffness factor, FKN)和修正摩擦系数,得到过盈量与摩擦系数间的对应关系,为同类转子的模态精确分析提供参考。针对磁悬浮转子是否考虑接触效应进行对比分析,结果表明考虑接触效应能够有效提高模型的精度,求解更准确。

关键词: 模态分析, 接触效应, 磁悬浮转子, 过盈配合, 静力分析

Abstract: According to the too simple model and the large error problem of modal analysis for traditional magnetic levitation rotors, the contact effect between the rotors was considered. The contact finite element method was used to establish the finite element model of the interference fit of the magnetic levitation rotors. With the combination of theory and static analysis, normal stiffness factor was optimized. By modifying the friction coefficient, the relationship between the interference coefficient and the friction coefficient was obtained, which could provide reference for the similar rotors' accurately analysis of modal. A comparative analysis was made on whether the contact effect was considered for the magnetic levitation rotor. The results showed that it could make the model and the solution more accurate to consider the contact effect.

Key words: magnetic levitation rotor, interference fit, contact effect, static analysis, modal analysis
