Resumo: | |||||||||||||
Electromagnetic acoustic transducers (EMATs) generate ultrasonic guided waves which can be used in inspections. The development of equipment e protocols used in these inspections requires the realization of sweeps. These sweeps are procedures used to gather data in an organized way, making possible the test and comparison between different equipment and settings. Therefore, the easy with which these sweeps are made is key to the development of theses inspections technologies and non-destructive testing.
In this work a robotic manipulator was developed aiming to move these EMAT transduces while a sweep is being made. The automation of this procedure requires the integration of mechanical, electrical and software components. This capstone project explores the basic concepts of EMAT transduces and the sweeps that uses them. The modeling and construction of mechanical hardware is discussed, with emphasis given to some problems that were encounter, and the utilization of components made with fused deposition modeling (FDM) 3D printing technology. It also presents the development of the electrical components need to the manipulator’s operation and the adaptation of existing software to the project specificities. At last, some results gathered with the develop tools are shown and compared to manual acquisitions. The conclusion reached was that the arm worked as expected. Although there are some points to evolve, it was possible to reliably make screenings with less than a third of the usual necessary time. Other than that, some recommendations for future development are made.
