Abstract
Synchronization phenomenon appears in many natural systems including physical, chemical and biological processes. In brief, synchronization may be understood as a harmonization of two or more system behaviors following some common pattern. Synchronized patterns depend of the dynamical characteristics of the system and, among these possibilities, there is the chimera state that consists in a symmetry break in the behavior of identical oscillator network. This paper deals with synchronization analysis of a mechanical pendulum-chart system composed by an hierarchical network of three pendula coupled to each other through their own chart that receive continuous supply of energy via a base excitation. Equations of motions are established and numerical simulations carried out considering the Runge-Kutta fourth order method. In this work Some patterns are classified and investigated in order to understand the necessary conditions to each pattern and to describe the result of a hyperchaotic chimera state. Results indicate that there are not any direct relation between the periodicity and non-periodicity with the patterns formed.
