ABSTRACT

Hydrodynamic journal bearings under steady conditions were discussed in the

previous chapters. The equations for pressure wave and load capacity were

limited to a constant, steady load and constant speed. Under steady conditions of

constant load and speed, the journal center is at a stationary point defined by a

constant eccentricity and attitude angle. Under dynamic conditions, however,

such as oscillating load or variable speed, the journal center moves relative to the

bearing.
