Ao longo deste relatório, pretende-se chegar um bocadinho mais perto daquilo que é o seu objetivo: projetar, modelar e analisar um kayak.
Hoje em dia, existem várias maneiras de fabricar protótipos, à escala 1:1 ou em escala reduzida / ampliada, e um dos métodos mais utilizados é usar impressoras 3D, visto que conseguem de maneira rápida imprimir objetos às diversas escalas para assim se conseguir efetuar uma análise.
No caso em apreço, este método é aplicado ao fabrico de um kayak. Pretende-se saber se existem diferenças significativas, ainda que analisadas visualmente, entre o protótipo e o modelo criado em software Solidworks de desenho 3D.
Com os modelos, deseja-se conseguir retirar vários parâmetros, nomeadamente a força e o coeficiente de arrasto. Para isto é necessário recorrer à extensão do software Solidworks, denominada de Flow Simulation, capaz de simular as mais diversas áreas relacionadas com mecânica dos fluídos. No caso dos resultados experimentais laboratoriais, serão calculados através de ensaios realizados no canal hidráulico, também capaz de simular condições aproximadas à realidade.
Finalmente, após todo o processo, é necessária a comparação dos resultados dos diferentes métodos e realmente ver se é um método viável, e se o kayak tem uma simetria adequada para o uso quotidiano.
Throughout this report, the main objective is to get a little closer to what its goal is: to design, model and analyze a kayak. Nowadays, there are several ways to manufacture prototypes, at 1: 1 scale or in a reduced / enlarged scale, and one of the most used methods is to use 3D printers, since they can quickly print objects at different scales in order to be able to do an analysis. In the present case, this method is applied to the manufacture of a kayak. The intention is to know if there are significant differences, even if analyzed visually, between the prototype and the model created in Solidworks 3D drawing software. With the models, it is desired to be able to reach several parameters, namely the force and the drag coefficient. For this, it is necessary to use the extension of Solidworks software, called Flow Simulation, capable of simulating the most diverse areas related to fluid mechanics. In the case of the laboratory experimental results, they will be calculated through tests performed in the hydraulic channel, also capable of simulating approximate conditions to the reality. Finally, after the whole process, it is necessary to compare the results of the different methods and actually see if it is a viable method, and if the kayak has a symmetry suitable for everyday use.
