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.
