Research On The Permanent Magnetic Bearing Simulation System Of Ultra Centrifuge

Bearings are the crucial parts in centrifuge, and play an important role in supporting the shaft and the shafting components, and reduce the friction of the relative motion skin. With the further research on the permanent magnetic bearing (PMB) and the broader application field being extended, using the PMB to supersede the general bearing will pioneer a new domain for the research on the bearing while the ultra centrifuge rotates in high speed. The unprecedented progress in permanent magnetic material studies leds PMB performance research thorough. The renovation of modernistic manufacture mode renovates the conventional design mode.The application of PMB on centrifuge high speed rotor system is studied in this thesis based on gathering datum widely and analyzing the actual state of research and development in centrifuge and PMB at domestic and foreign, and some correlation studies, with visualization modeling and simulation technique. Consulting one configuration of designed PMB, the series'data of this configuration and the 3D simulated model database of these series are established, according to series diameter of centrifuge centre pivot. The permanent magnetic field, carrying capacity, limit speed and critical speed of this PMB are studied thoroughly,too.The simulation system is developed by VB, mostly includes the 3D simulated model building, the prototype production and the finite element analysis calculates three modules. The 3D parameterized model and the virtual prototype automatic modeling are realized through the modeling software SolidWorks re-developed with VB. The performance of PMB automatic analysis is realized by ANSYS software re-developed with VB and APDL unify.The developed PMB simulation system, under the different design parameter, is advantageous for the PMB to rebuild the model fast, and carry on the finite element simulation analysis. The above conclusion and the method have enriched the super centrifuge and the PMB research content, and explored a lower consumption higher quality design and analysis method for high speed rotor system. So this topic research has the certain project practical significance.
