Abstract:
The sizing of bolted joints is crucial for mechanical projects that will experience working loads. This requires careful analysis during the design specification phase, where materials, manufacturing processes, components, and layout are determined. This analysis is time-consuming since most of it is done manually using analytical calculations, as there are limited computational tools available. Developing such tools requires a formal representation of knowledge that algorithms can process. The purpose of this work is to create a conceptual model, using ontologies, to represent the information found in specialized literature about bolts and bolted joints. By doing so, it becomes possible to automate calculations for bolt stiffness and stiffness of joint elements. The ontology was built following the UPON methodology, which involves extracting domain terms to guide knowledge modeling. The resulting ontology provides a formal and explicit representation of statically loaded bolted join
ts in an axial direction. It also has the capability to answer predetermined competence questions, indicating that it can be used by software applications to process information efficiently.
