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

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; 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).
