Magneto-Mechanical Model of Passive Magnetic Axial Bearings versus the Eccentricity Error, Part II: Application and Result

摘要

In this paper we apply the physical mathematical model described in Part I [1]. The study shows i) the influence of the eccentricity of two polarized rings of the bearing on the stiffness, ii) the numerical efficiency of the response surfaces for evaluating the magnetic field in any point of the domain fixed, and iii), in relation to a demanding application example (possible replacement of a big axial oleodynamic bearing with a thrust magnetic passive bearing), the danger arising from possible resonances (the natural frequencies of the device are near to the excitation frequencies).
