Resumo(s)
O anteprojeto é uma fase de grande importância na realização de um novo projeto, sendo este esclarecedor de toda a estrutura, mecanismos e componentes do produto em desenvolvimento. Esta fase também define os maiores custos envolvidos na realização do projeto, aumentando assim a sua importância na conceção de um projeto. Neste momento, existem várias metodologias para a conceção de anteprojetos para equipamentos mecânicos, porém nenhuma destas consegue ser aplicada para todo o processo. Assim, é fundamental designar a melhor metodologia para cada fase do anteprojeto, de forma a obter-se um anteprojeto sólido e bem estruturado.
Numa primeira instância, foram abrangidas algumas das metodologias mais utilizadas nos anteprojetos, e foi realizada uma comparação entre as mesmas, tendo como intuito perceber e escolher qual a melhor metodologia para cada fase. As metodologias abrangidas nesta dissertação foram: Teoria Axiomática; Matriz de Decisão; QFD; AHP; TRIZ; Modelo de Kano; e, Brainstorming. Posteriormente, foram estudados dois procedimentos necessários para a conceção de anteprojetos, os Modelos Teóricos Simplificados e a Modelação Matemática.
Na fase final, foi desenvolvida uma metodologia para a conceção de anteprojetos para equipamentos mecânicos. Esta utiliza alguns dos métodos estudados anteriormente, como o Modelo de Kano, o Brainstorming, a Teoria Axiomática e a Matriz de Decisão. A metodologia desenvolvida é de fácil utilização e pode ser aplicada em todo o anteprojeto, diferenciando-se de todos os métodos existentes abrangidos neste trabalho. Ainda nesta fase, foi aplicado um exemplo simples, de forma a ilustrar e orientar a utilização desta metodologia para anteprojetos futuros de equipamentos mecânicos.
The conceptual design is one of the most important phases in the fulfilment of a new design, wich clarifies the entire structure, mechanisms and components of the product under development. This phase also defines the highest cost, thus increasing it's importance in the completion of the design. Nowadays, there are several methodologies that can be used to complete the conceptual design for mechanical equipments, but none of these can be applied for the entire process. Therefore, it is essential to designate the best methodology for each phase of the conceptual design, in order to obtain a solid and well-structured design. At first, some of the most commonly used methodologies in conceptual design were covered and a comparison is made between them in order to understand and select the best one for each phase. The methodologies covered in this thesis were: Axiomatic Design; Decision Matrix; QFD; AHP; TRIZ; Kano Model and, Brainstorming. Subsequently, two procedures necessary for the design of conceptual design: Simplified Theoretical Models and Mathematical Modelling. The final stage was developed a methodology for the design of mechanical equipment conceptual design. This was used some of the methods studied previously, such as Kano Model, Brainstorming, Axiomatic Design and Decision Matrix. The methodology developed was easy to use and could be applied to the entire conceptual design process, after that differentiating it from all the existing methods covered in this thesis. Also at this stage, a simple example was applied to illustrate and guide the use of this methodology for future mechanical equipment conceptual design.
