Dynamic Coefficients of Finite Length Journal Bearing. Evaluation Using a Regular Perturbation Method [PDF]

open access: yes, 2019
A set of simple expressions is deduced for static and dynamic parameters associated to hydrodynamic journal bearings (JB). The behavior of this system is governed by two dimensionless numbers, the aspect ratio, L/D, and the eccentricity ratio, η.
