Stability Analysis of Twin Axial Groove Hybrid Journal Bearing

Stability Analysis of Twin Axial Groove Hybrid Journal Bearing

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 centr...
