Resumo: The automotive industry requires continuous innovation in order to fight the high competitiveness in this sector. More than ever, fuel economy, low emissions and comfort are the main goals when designing a vehicle. Continuously Variable Transmissions (CVT) are a type of transmissions that meet with those features and it can be the future of automatic transmissions. The presented dissertation was developed during an internship in a company, specialist in the development and production of CVT transmissions, designated by Punch Powertrain NV, located in Sint-Truiden, Belgium. The work was incorporated in the Research and Development (R&D) department, in the team of simulation, where it was possible to enhance the academic experience. This work is based on a need to post-process the results of several measured and simulated scenarios. Firstly, it was proposed to analyse the interference between the components of a hydraulic block. After the block is simulated individually, the inside walls can deform and it is important to analyse if there is interference with the movable components. Secondly, there are corrections done on gears. These corrections are evaluated through gear measurements, which need to be processed to determine if the modifications are within the nominal parameters. The last task was to analyse exported data from road load tests. In each transmission, five accelerometers are installed that record the loads subjected in the three coordinates. These files are read and, then, processed using an algorithm of a counting method, that can predict the cycles of each accelerometer for the different loads. All results are validated by the team leader and the specialists of each field. In the end, the internship allowed to increase the knowledge obtained from the Master’s.

Mais do que nunca, economia de combustível, baixas emissões e conforto são as principais características na hora de desenhar um veículo. Transmissões Continuamente Variáveis (CVT) são um tipo de transmissão que cumpre esses objetivos e pode ser o futuro das transmissões automáticas. A presente dissertação foi desenvolvida durante um estágio numa empresa especialista no desenvolvimento e produção de transmissões CVT, com o nome de Punch Powertrain NV e localizada em Sint-Truiden, Bélgica. O trabalho foi inserido no departamento de Inovação e Desenvolvimento (I&D), na equipa de simulação, onde foi possível enriquecer a experiência académica. Este trabalho teve por base a necessidade de pós-processar os resultados de diversos cenários medidos e simulados. Em primeiro lugar, foi proposto analisar a interferência entre os componentes de um bloco hidráulico. Depois do bloco ser simulado individualmente, as paredes interiores podem deformar e é importante analisar se existe interferência com as componentes móveis. Em segundo lugar, existem correções feitas em rodas dentadas, para que possam trabalhar corretamente. Então, estas correções são analisadas através de medições, que precisam de ser processadas para determinar se as modificações estão dentro dos parâmetros nominais. A última tarefa foi analisar informação exportada dos testes de carga na estrada. Em cada transmissão, são instalados cinco acelerómetros que registam as cargas submetidas nas três coordenadas. Esses ficheiros são lidos e, depois, processados usando um algoritmo de contagem, que consegue prever os ciclos de cada acelerómetro para as diferentes cargas. Todos os resultados são validados pelo líder de equipa e pelos especialistas de cada área. No final, o estágio permitiu aumentar o conhecimento obtido durante o mestrado.Silva, Francisco José Gomes daRepositório Científico do Instituto Politécnico do PortoMartins, Luís António Salvador2021-10-30T00:30:23Z20182018-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.22/12675TID:202026418enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-03-13T12:54:40Zoai:recipp.ipp.pt:10400.22/12675Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T17:32:59.263886Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
