Investigation on macro fiber Composite based smart structure Using finite element analysis

Abstract

NASA Center for Space Research invented a Macro-Fiber Composite (MFC) device as actuator and sensor for energy harvesting and vibration control. The MFC is primarily made up of piezo ceramic fiber rods that have been dipped in epoxy resin and are sandwiched between Acrylic and Kapton layers. A piezoelectric patch for active vibration control is a difficult technology to use to alleviate vibration issues. The major studies of MFC are focused made on experimental quantification of piezoelectric, dielectric and actuation properties. The majority of research has focused on cantilever beams and plates. The first structure of a cantilever beam is modelled, analyzed, and structural vibration is used as sensing and actuation in this investigation. The Theoretical model of the beam and the FE model are derived to select the suitable based on dimensions, shape and substrate materials for energy harvester and actuation control simulations of the cantilever beam with MFC. The controller designed in the simulation stage is examined and analyzed through experimental activity. The structure, on the other hand, is used as a test to assess the electric field produced by the device as a result of natural frequencies. Next, a geometrical variation of cantilever beam with MFC patch are evaluated the performance of MFCs for actuation and control using closed loop circuit. In order to convert the voltage of direct current, alternating current must be processed the input sources to the MFC using rectifier circuit. Both types of currents are maximized in this study by altering the capacitance and voltages values newline
