Resumo

This paper present computational method in the Matlab environment for numerical simulation and analysis of the ordinary differential equations of the nonlinear dynamics of mechanical and electromechanical systems. As a motivation for the study, the differential equations studied are mathematical models of collecting devices of energy present in existing vibrations in the environment. In particular, there is a model of on board pendulum (in a naval vehicle), which for certain parameters and initial conditions, can present a permanent rotation regime that can be used for electric power generation.
