Abstrakty
The equivalent stiffness and damping coefficients calculated successively along the journal center locus with reference to the equilibrium position are obtained (in the case of stable journal orbit) using Taylor series expansion. To validate the accuracy of the derived coefficients, the journal orbit is compared with the transient simulation under similar operating conditions. The equivalent dynamic coefficients are further evaluated according to the modified journal position using linear interpolation procedure. The average value of the equivalent stiffness and damping coefficients are calculated at various perturbation amplitudes from equilibrium position along the transient orbit. The influence of journal center position and velocities is observed. With nonlinear coefficients close to actual simulation under stable conditions this methodology provides the bearing designer variation of dynamic coefficients in the bearings.
