The main objective of this thesis is the development of parameter representations which are interconnected in flexible rotor and autobalance systems coupled. This goal consists in achieving independent set of differential equations for each section of the shaft and applying stiffness method to obtain a global matrix. These models have been used to analyze elastic and inertial properties of rotors. After we obtain a global matrix, we can establish a set of differential equations, which may be simulated by software and analyzed stability and dynamical behavior of our complete system. Inertial associated coefficients have been founded in this model, by the way; effects by each section and connections have been gotten. Dynamical behavior of balls and rotor has been analyzed by Lagrange method to get a differential equations system. In the case of a single rotor and a single drum (with balls) in different plane, an experimental model was developed; theoretical (software) and experimental results were similar, and this showed the efficiency of the balancing method. There are several conditions of mass, stiffness and frequency which system works, these characteristics were founded.

Keywords : Autobalance system; Lagrange.
