## Abstract Dynamic equilibrium equations of structural systems with nonβproportional damping are coupled through the damping terms. Such coupling invalidates application of the classical modal superposition method. In this paper, a modeβsuperposition pseudoβforce method is proposed. The coupled eq
Mode-superposition analysis is an efficient tool for the evaluation of the response of linear systems subjected to dynamic agencies. Two well-known mode-superposition methods are available in the literature, the mode-displacement method and the mode-acceleration method. Within this frame a method is
In this paper, a solution method is presented to solve the eigenproblem arising in the dynamic analysis of non-proportional damping systems with symmetric matrices. The method is based on the Lanczos method to generate one pair of Krylov subspaces consisting of trial vectors, which is then used to r
The method of multiple scales is developed to analyze the free and forced vibration of non-linear rotor-bearing systems. The rotating shaft is described by the Timoshenko beam theory which considers the effect of the rotary inertia and shear deformation. A non-linear bearing pedestal model is assume
