Ontologia para auxílio no dimensionamento de junções parafusadas

Abstract

The sizing of bolted joints is of great importance for mechanical projects, in which they will be subject to working loads. This sizing demands careful analysis during the design specification phase, in which materials, manufacturing processes, components, and their layout are defined, thus demanding a lot of time from the design team. In addition, most of the analyses are performed manually, through analytical calculation methods, as there are few computational tools that include these procedures, since their development requires a formal representation of knowledge, making it processable by algorithms. Therefore, the present work aimed to conceptually model (describe at a semantic level), through a representation using ontologies, the information found in specialized literature, referring to bolts and bolted joints, making it possible to automate the bolt stiffness and joint elements stiffness calculations. The ontology building followed the UPON methodology, which mainly consists of extracting domain terms to guide the knowledge modeling. Thus, the resulting ontology contains a formal and explicit representation of bolted joints loaded statically and in an axial direction, as well as being able to answer pre-established competence questions, which indicates that it enables the processing of the information by the softwares that will utilize it.
