AB - In this paper, both the steady-state and transient-state of the films flow  are investigated by CFD. The journal bearing dynamic characteristics such as  the load capacity, damping and stiffness coefficients for several  eccentricity, and length over diameter ratio (L/D) are obtained and compared  with each other in different working conditions. Furthermore, the variation  of various research parameters with eccentricity and L/D are also illustrated  in detail.
