Abstract(s)
Os veículos motorizados, de duas e quatro rodas, são o suporte de mobilidade da sociedade. Uma vez que estão presentes em grande escala, é de todo o interesse garantir a sua circulação com a maior segurança, no sentido de proteger o utilizador e o próprio veículo. Estes veículos motorizados, para além de meio de transporte, também podem servir de objeto de lazer e competição, como por exemplo, a prática de todo terreno. Esta prática ocorre, na grande maioria, em terrenos irregulares e acidentados, onde a frequência de quedas é bastante elevada. Na sequência das múltiplas quedas, o que se têm observado na utilização destes motociclos, é a frequente deformação ou até mesmo, em situações mais gravosas, a rotura do radiador. Uma vez que a localização do radiador se encontra numa zona exposta a este tipo de impacto, surgiu a necessidade do desenvolvimento de uma proteção para o mesmo. O radiador é um componente mecânico que pertence ao motor. É um componente sensível e pouco tolerante a impactos, sendo considerada uma peça crítica que poderá colocar em causa a circulação do motociclo. É expectável que um praticante de todo terreno perceba a funcionalidade deste produto, não só como um acessório estético, mas essencialmente pela necessidade em proteger e preservar o estado do radiador, para garantir o bom funcionamento do motor após uma possível queda. O objetivo inicial era o desenvolvimento de uma proteção de radiador mas, devido ao surgimento do vírus COVID-19, os objetivos foram reajustados para: benchmarking e estabelecimento das diretrizes para o desenvolvimento de proteções de radiador alternativas para um motociclo de todo terreno. Assim sendo, foi realizada, numa fase inicial, uma análise de mercado que deu origem à definição dos requisitos que o produto deveria cumprir. Em seguida, foram adquiridas algumas amostras que se destacaram na análise de mercado com base nos requisitos que o produto deveria cumprir. Em paralelo à aquisição de amostras. estava a ocorrer o desenvolvimento de ensaio laboratorial, assim como a construção do equipamento para a realização do mesmo. Após a conclusão destas duas tarefas, deu-se início a uma análise exploratória exaustiva, com ensaios de montagem e ensaios de impacto, das amostras adquiridas. Por último, definiram-se as diretrizes para o dimensionamento de uma proteção de radiador, assim como as orientações/cuidados a ter na fase de dimensionamento da mesma.
Motorized vehicles, two and four wheels, are the mobility support of society. Since they are present on a large scale, it is of all interest to ensure their circulation with the greatest safety, in order to protect the user and the vehicle itself. These vehicles, in addition to being a means of transport, can also serve as an object of leisure and competition, such as off-road practice. This practice occurs in the vast majority, on irregular and rough terrain, where the frequency of falls is quite high. As a result of multiple falls, what has been observed in the use of these motorcycles is the frequent deformation our the rupture of the radiator. Since the location of the radiator is in an area exposed to this type of impact, the need to develop a protection for it arose. The radiator is a mechanical component that belongs to the engine. It is a sensitive component and not very tolerant of impacts, being considered a critical part that could jeopardize the movement of the motorcycle. It is expected that an off-road rider will perceive the functionality of this product, not only as an aesthetic accessory, but essentially due to the need to protect and preserve the condition of the radiator, to guarantee the proper functioning of the engine. The initial objective was the development of a radiator guard, but due to the emergence of the COVID-19 virus the objectives were readjusted to: benchmarking and establishing the guidelines for the development of alternative radiator guards for an off-road motorcycle. Therefore, in an initial phase, a market analysis was carried out, which gave rise to the definition of the requirements that the product should fulfill. Then, some samples were acquired that stood out in the market analysis based on the requirements that the product had to fulfill. In parallel with the acquisition of samples, the development of a laboratory test was taking place, as well as the construction of the equipment to carry it out. After the completion of these two tasks, an exhaustive exploratory analysis began, with assembly tests and impact tests, of the samples acquired. Finally, guidelines were defined for the dimensioning of a radiator protection as well as the guidelines/care to be taken in the dimensioning phase of the same.
