Hirani, H.; Athre, K.; Biswas, S. Transient trajectory of journal in hydrodynamic bearing. (English) Zbl 0964.76021 Appl. Mech. Eng. 5, No. 2, 405-418 (2000). A technique, based on analytical two-dimensional pressure distribution, is developed to determine the nonlinear journal trajectory under application of dynamic loads, including journal unbalance and inertia forces. The authors use a global Newton-Raphson method which ensures a fast convergence. The results for rod bearings indicate that, at high rotation speeds, inertia forces due to journal motion are significant and cause an increase in the journal eccentricity ratio.
