Abstract(s)
A utilização de impressão 3D como método de fabricação tem crescido nos últimos anos por conta da grande redução de tempo e custo quando comparada aos métodos tradicionais, além da liberdade na alteração do design e possibilidade de simulação dos modelos desenvolvidos. O objetivo deste trabalho foi fabricar um protótipo de um barco controlado remotamente e calcular as equações do movimento do mesmo. Foram realizadas a modelagem 3D e dimensionamento de um molde para posterior impressão em PLA, que foi utilizado para construir o protótipo por laminação em fibra de vidro. Com o auxílio do dimensionamento gerou-se as equações de movimento através do Método de Kane, utilizadas posteriormente para simular a trajetória de movimento do modelo ao longo do tempo. Foram ainda desenvolvidos algoritmos para efetuar o controle remoto e de movimento do protótipo utilizando módulos de comunicação por rádio frequência e outros componentes eletrônicos. Os componentes eletrônicos foram montados no protótipo construído e foi possível estabelecer a comunicação e movimento entre os elementos. O processo de laminação em fibra de vidro foi bem sucedido, porém devido instabilidades durante a transmissão de dados entre os módulos de comunicação, não foi possível colocar o protótipo na água para validação do projeto.
application of 3D printing as manufacturing method increased in the last years motivated by the loss of time and money when compared with the traditional manufacturing methods, as well as the freedom in the design modifications. The goal of this work was to build a remote-controlled boat prototype and to calculate its equations of motion. The 3D modelling and dimensioning were conducted in order to manufacture a 3D printed PLA mould, which was used to make a fiberglass model. The data provided by the dimensioning was used to calculate the equations of motion through the Kane’s Method, with which was possible to simulate its trajectories of movement through time. Algorithms were develop to perform the remote and movement control of the prototype with a radio-frequency module and electronic components. The electronic components where assembled inside the prototype and became possible to establish the communication between the elements. The lamination process was successful, but due to instability during data transmission between the communication modules, it was not possible to put the prototype in the water for validation of the project.
