“…The static parameters of the rubber cushion and magnetic field and the deformation of the pad's working layer are solved using the Finite Element Method (FEM) [28][29][30][31]. By applying the magnetic force as well as the rubber elastic force and moment into the fluid governing equation, the static parameters of the fluid field are solved using the Finite Difference Method (FDM) [32][33][34]. When the convergence condition is reached, the model is solved to obtain the load-carrying characteristics of the MWETB.…”

Aiming at the problem that the traditional water-lubricated bearing cannot carry the heavy load and adapt to the constantly changing operating conditions for the high-power Rim Driven Thruster (RDT), the principle structure of the Magnetic Water-double-suspension Elastic-support Thrust Bearing (MWETB) is designed and the optimal structure parameters of the bearing are selected using simulation. To demonstrate the reliability of the MWETB under the RDTs’ actual working conditions, performance tests, which include the magnetic flux density, magnetic force, and lubrication performance, are carried out. The simulation and experimental results indicate that the optimal offset ratios are in two intervals, and the magnetic alignment and sheath materials have a great effect on the load reduction. The load-carrying force has obvious zoning characteristics with the change in bearing clearance. Besides, compared with the water-lubricated thrust bearings, the MWETB has advantages in terms of minimum film thickness and friction coefficient.

“…However, this increases the complexity of the FEM problem since a larger part of the geometry (if not full) must be included if the shaft is rotating off center. As seen in recent publications, the radial orbits for a passive magnetic bearing can vary greatly with rotational speed [13].…”

Abstract. Two types of passive magnetic lift bearings were evaluated in terms of thrust force and eddy current losses. The first type of bearings were based on two sets of segmented Halbach arrays mounted in repulsive mode, and the second type was based on ring-magnets. The eddy-currents studied arose in the bearing due to manufacturing variations of magnetic remanence, and due to non-radial magnetization. Both a 3D time-dependent and a quasi-stationary Finite-Element Method (FEM) formulation were used, and the simulated results were compared with lift-force measurements from experiment. The losses were found (by FEM) to be in the order of 25 W at a rotational speed of 30000 rpm while lifting a 45 kg rotor with a stiffness of 359 N/mm.
