چکیده
|
Stability of rigid rotor supported on hybrid journal bearing with twin axial groove has been investigated using stiffness and damping coefficients of the bearings. in this paper the stability analysis of twin axial groove bearing is determined in different fluid flow regime. non linear journal centre trajectories are drawn for small amplitude oscillations of the journal centre about its steady state position. it was observed that turbulence decreases 10 to 12 percent the stability margin of twin grooved journal bearings.
