NUMERICAL INVESTIGATION ON DYNAMIC CHARACTERISTICS OF HYDRODYNAMIC BEARING

ABSTRACT
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.
