Numerical Simulation and Optimization Design for Magnetic Fluid Sealing Device
In this paper the principle of magnetic fluid seals is discussed. Based on the finite element software ANSYS, the magnetic field of magnetic fluid sealing device with three slots and four pole teeth is analyzed, and the size parameters of magnetic fluid sealing pole are optimized. The results show that the difference between the maximum and minimum intensity of magnetic field in the area near the shaft determine the sealing capacity of sealing device. The gap of seal should not be larger than 0.3mm. The optimized parameters which are provided for practical design can increase sealing capacity of sealing device as well as decrease the volume of sealing device.
Numerical analysis on the action of centrifuge force in magnetic fluid rotating shaft seals
The magnetic fluid seal is suitable for high-speed rotating shaft seal applications. Centrifuge force will have evident influence on magnetic fluid rotating shaft seals. The seal capacity of the rotating shaft seal can be improved or increased by some measures. Through hydrodynamic analysis the moving status of the magnetic fluid is worked out. By numerical method, the magnetic field and the isobars in the magnetic fluid of a seal device are computed. Then the influence of the centrifuge force on the magnetic fluid seal is calculated quantitatively.
Magnetic fluid mechanics: a report on an International Advanced Course and Workshop
An International Advanced Course on the Thermomechanics of Magnetic Fluids was held from 3 to 7 October 1977 at the International Centre for Mechanical Sciences (CISM), Udine, Italy, under the direction of B. Berkovsky. The course was a joint CISM/UNESCO undertaking and its general objectives were to assess knowledge in the field, to identify specific problem areas and promising directions for future research and applications, and to assist in the establishment of active relations between national research groups. It was the first conference to bring together the diverse and dispersed community of researchers in the field; there were 34 participants from 16 countries and 19 papers were included in the programme.
