A simple methodology to trace journal orbit under dynamic load conditions is presented. The non-linear fluid film bearing forces are derived using a closed-form two-dimensional pressure solution obtained from Reynolds equation for dynamic case. An implicit two-dimensional Newton-Raphson method is employed to determine journal center velocity by solving the equations of motion incorporating journal inertia and unbalance forces. A global technique is used to ensure convergence towards the root in each iteration. Finally, two connecting rod big end bearings are studied to demonstrate the effect of inertia forces at high speed.
