Abstract
It is a purpose of this paper to present a means of handling both turbulent and inertia effects on the dynamic characteristics of finite width journal bearings. In the analysis turbulence is treated by means of turbulent coefficients and inertia forces are approximated by mean velocities averaged across the fluid film. Assuming a small displacement of journal center, the dynamic coefficients such as spring, damping and acceleration coefficients and the onset whirl frequencies of rotors are computed The results obtained show that the dynamic characteristics as mentioned above are affected by inertia forces.
