Stability analysis by the reduction model was developed in order to analyze the stability of the periodic steady-state vibrations generated in a nonlinear large scale structures by applying the concept of modal analysis to analysis of variational equation with periodic coefficients. By applying this method, the computation cost for stability analysis is remarkably reduced and stability of the periodic steady-state vibrations can be computed with high accuracy. By the way, the equation of motion of an unsymmetrical shaft with unsymmetrical supports becomes linear simultaneous ordinary differential equation with periodic coefficients. In this report, the concept of the stability analysis by the reduction model is applied to the stability analysis for an unsymmetrical shaft with unsymmetrical supports. At first, an algorithm based on the present method is formulated. Next, the validity of this method is confirmed by the numerical computational results.
