Análise da capacidade de captação de energia piezoelétrica de um sistema aporticado acoplado a um dissipador de energia não linear

Abstract

The purpose of this work is the mathematical and computational study of an electric power generation system through the use of piezoelectric materials coupled to a porticoed system, this system is framed in the nomenclature of energy collection, being the methodology of electric power generation through reuse of energy dissipated by an existing system, in the case of this work the energy dissipated is in the form of system vibration. The starting point for this work was the world's need for electrical means of power generation, and the need to store electricity in systems that are difficult to access, such as pacemakers or serviced probes, where maintenance becomes impracticable, which is why the The search for means of energy collection has become comprehensive, being a field widely researched today, so it was decided to mathematically and computationally analyze the variables of the port system. It was performed to analyze the variables to determine which has the greatest influence on the system's energy generation and to determine the existing mathematical optimum point in the search interval. The purpose of the research is to determine the optimal point for generating electricity in the system, pointing out which variable is most significant and how it influences the system as a whole.
