Resumo
Os transportes rodoviários de carga no Brasil vêm crescendo exponencialmente ao longo dos anos, chegando ao ponto de em 2019 termos 61% desse modal como responsável pelo transporte de carga no Brasil e tendo sua frota avançado 2.5% no ano de 2022, visto que o país é um dos maiores em transportes de cargas do mundo. Na tendência mundial, a eletrificação dos veículos de carga não são exceção, com o primeiro dessa categoria já à venda no país e previsões de um futuro com frotas 100% elétricas (IBGE, 2019). O Brasil é tido como um país de proporções continentais tendo sua maior rodovia, BR116, com 4660 km ligando a região nordeste ao sul do país, visto que o percurso sem abastecimento é amplo, pensamos em carros elétricos como uma maior insegurança do público em geral, visto que a autonomia se torna não mais apenas um ponto de economia, mas sim uma necessidade, e desta nasce a ideia dos freios regenerativos, que fazem uso da energia não útil no momento de frenagem para o armazenamento da energia para usos futuros. (Regenerative Braking Systems, 2021). Pensando nisso o Thunder Brake propõe um sistema modular, composto por flange simples ranhurada e dupla adaptada com um motor elétrico, de fácil implementação que ao ser acoplado a ponta de eixo em caminhões e reboques, permitirá a recuperação de energia cinética, auxiliando na frenagem do veículo e gerando energia por meio da ideia de freio regenerativo. Para este projeto, foram utilizados os princípios de mecânica dos sólidos afim de determinar deformações e tenções nos acoplamentos assim como seu dimensionamento, para análises mais precisas foram realizadas simulações pelo método dos elementos finitos via Ansys gerando resultados gráficos e análises visuais intuitivas e de fácil compreensão. Também foi proposto, através de logica fuzzy, uma breve simulação comportamental do sistema, sendo toda modelada através do Mathlab, gerando assim superfícies de controle e um modulo interativo onde pode se estudar o efeito das curvas de influência determinadas para a simulação.
Road freight transportation in Brazil has been growing exponentially over the years, reaching the point that in 2019 we had 61% of this mode responsible for cargo transportation in Brazil and having its fleet advanced 2.5% in the year of 2022, since the country is one of the largest in cargo transports in the world. In the global trend, the electrification of cargo vehicles is no exception, with the first of this category already for sale in the country and predictions of a future with 100% electric fleets (IBGE, 2019). Brazil is considered a country of continental proportions having its largest highway, BR-116, with 4660 km connecting the northeast region to the south of the country, since the journey without refueling is broad, we think of electric cars as a greater insecurity of the general public, since autonomy becomes not just an economy point, but a necessity, and from this the idea of regenerative brakes is born, which make use of the non-useful energy at the time of braking for storing energy for future uses. (Regenerative Braking Systems, 2021). Thinking about this, Thunder Brake proposes a modular system, composed of a simple grooved flange and double adapted with an electric motor, easy to implement that when coupled to the axle end in trucks and trailers, will allow the recovery of kinetic energy, assisting in the braking of the vehicle and generating energy through the idea of regenerative brake. For this project, the principles of solid mechanics were used in order to determine deformations and tensions in the couplings as well as their sizing, for more precise analyses simulations were carried out by the finite element method via Ansys generating graphic results and intuitive visual analyses and easy to understand. It was also proposed, through fuzzy logic, a brief behavioral simulation of the system, being all modeled through Mathlab, thus generating control surfaces and an interactive module where one can study the effect of the influence curves determined for the simulation.
