Abstract:
This article considers the effects of non-linearity in the dynamic properties of
a journal bearing and presents a method of constructing the calculations needed
in the identification of a non-linear dynamic model of the oil film. The new
calculation method, together with its background and development is described
and illustrated. The method uses frequency-domain descriptions of the test
waveforms and accommodates any reasonable oil film model. It can also be used to
predict the orbits. It has been applied to both theoretical and experimental
results, and a robust procedure based on the new calculation method for the
extraction of higher-order dynamic oil film coefficients is proposed and
described.
