| 摘 要： | 永磁轴承悬浮时的受力,与磁轴承的结构及永磁体材料参数有关。针对一种新型径向磁化船用永磁推力轴承,依据虚位移法,得出了轴向承载力与轴向刚度解析模型,并通过有限元仿真与实验得出了漏磁系数取值。利用有限元法和实验对轴向承载力与刚度进行验证,解析结果与验证结果基本吻合。

| Abstract: | The force of permanent magnetic bearing in suspension is related to configuration of permanent magnetic bearing and the material parameters of permanent magnet. According to a new radial magnetized marine permanent magnetic thrust bearing (PMTB). The analytical calculation of axial bearing capacity and axial stiffnessis was derived by virtual displacement method. With the finite element simulation and experiment, the value of magnetic flux leakage coefficient is obtained. The results of simulation and experiment are basically in agreement with the analytical results. |
