摘要

The proper sizing of bolted joints is essential in mechanical projects that are subjected to operational loads. This process requires thorough analysis during the design specification phase, where decisions regarding materials, manufacturing processes, components, and layout are made. Conducting this analysis can be quite time-consuming, as it largely relies on manual analytical calculations due to the scarcity of available computational tools. Developing such tools necessitates a formal representation of knowledge that can be processed by algorithms. This study aims to develop a conceptual model, named OntoJoint, utilizing ontologies to represent the information found in specialized literature concerning bolts and bolted joints. This approach facilitates the automation of calculations related to bolt stiffness and the stiffness of joint elements. The ontology was constructed using the UPON methodology, which involves the extraction of domain-specific terms to guide knowledge modeling. The resulting ontology, OntoJoint, offers a formal and explicit representation of statically loaded bolted joints in the axial direction. It is also capable of answering predefined competence questions, demonstrating its potential for use in software applications to process information efficiently. Additionally, the proposed OntoJoint ontology was evaluated in an educational tool, further validating its applicability.
