Identificação dos parâmetros de um rotor flexível

Abstract

This contribution is a study of the behavior of a flexible rotor in a computing environment to identify the parameters of stiffness and damping. The rotor shaft is modeled using finite elements using the method of Timoshenko beam element, having the following features: the element has two nodes; each node has four degrees of freedom, i.e. two degrees of displacement and two degrees rotation. Then, was applied one of various optimization methods used in inverse problem for parameter identification. In this case, the method used was the differential evolution.
