| 英文摘要: |
| This paper analyzes the sources of heat losses in magnetic fluid bearings, proposes various cou-
pling relationships of physical fields, divides the coupled heat transfer surfaces while ensuring the
continuity of heat flux density, and analyzes the overall heat dissipation pathways of the bearings. By
changing parameters such as input current, rotor speed, and inlet oil flow rate, the study applies a
multi-physics field coupling method to investigate the influence of different parameters on the temper-
ature field and heat dissipation patterns of the bearings, which is then validated through experi-
ments. This research provides a theoretical basis for the optimal design of magnetic fluid bearing sys-
tems. |
