RESUMO

It is described in this work a Bond Graph based procedure to the development of linear mechanical systems reduced order models. From the analysis of the topological structure of the main mechanical models represented by this technique it was established a new formulation that permits to obtain several mathematical representation forms and it was defined a generic graph, formed by energy storage and dissipative hiperfields, where the matrices that characterizes the system dynamics are included. On the generic graph, with some constraints, it was applied a methodology for the normalization and decoupling of the energy storage fields, based on its local modes, that permits to develop a partioned graph, couplec through the dissipative field. The analysis of the coupling field coefficients permits to define the system Reduced Bond Graph. The procedure was comproved by easy comprehensive examples.
