DYNAMIC CHARACTERISTICS OF MAGNETIC FLUID BASED SLIDING BEARINGS

摘要

The dynamic behaviors of magnetic fluid-lubricated slider bearings have been investigated in this paper. For the slider bearing with an inclined film profile, the use of magnetic fluids as lubricants is found to provide an increase in the load carrying capacity, and the stiffness and damping coefficients as compared to the case of a conventional viscous fluid. The dynamic characteristics of slider bearings are improved by using magnetic fluid lubri-cants together with the application of magnetic fields.
