Foil Bearing Investigation. A Foil Bearing Model for High Speed Rotating Magnetic Head.

摘要

A quasi one-dimensional foil bearing model for high speed rotating magnetic heads has been formulated. Side flow is smeared as a leakage factor. Steady state foil inertia effects are included. The effects of head protrusion side leakage factor as well as speed parameter are discussed. Of particular interest is the effect of rotational speed in relation to the propagation speed of transverse waves in the foil. (Author)
