... coordinate systems are built up in matrix form. A fast algorithm using the NewtonRaphson method for calculating the equilibrium position of journal and pads is proposed. The eight reduced stiffness and damping coefficients can be obtained assuming that the journal and all pads are subject to harmonic...
