چکیده

The high magnetic energy stored in rare earthcobalt magnets a 11 ows the design of 1 i ght~tei ght motors and magnetic bearings for high speed rotors. Not subject to wear and 11i th the abi 1 i ty to operate under high vacuum conditions, magnetic bearings appear ideal for applications requiring high rotational speeds such as 100,000 rpm. Important applications are for turbomolecular pumps, laser scanners, centrifuges, momentum rings for satellite stabilizations, and other uses in space technology. It is the purpose of this paper to present a two-dimensional nonlinear numerical analysis of the magnetic fields in a magnetic bearing, based on magnetostatic assumptions and finite-difference iterative techniques.

Nonlinear Nonlocal Vibration of an Embedded Viscoelastic Y-SWCNT Conveying Viscous Fluid Under Magnetic Field Using Homotopy Analysis Method

In the present work, effect of von Karman geometric nonlinearity on the vibration characteristics of a Y-shaped single walled carbon nanotube (Y-SWCNT) conveying viscose fluid is investigated based on Euler Bernoulli beam (EBB) model. The Y-SWCNT is also subjected to a longitudinal magnetic field which produces Lorentz force in transverse direction. In order to consider the small scale effects,...
