Application of a Geometric Common Model Modeling Method Based on Skeleton Model in Lashing Bridge Design

The lashing bridge is considered one of the core technologies in container ships. It is used to secure containers above the main deck and transfer the loads generated by container stacking to the ship’s structure. Its design is influenced by various factors. Therefore, it faces challenges in terms of design changes and collaborative design. In addition, lashing bridge design not only requires generating drawings and bill of material (BOM), but also involves activities such as finite element analysis and virtual prototyping validation, all of which have different geometric requirements. This paper proposes a product structure built upon the concept of geometric common modeling, leveraging skeleton models within the CATIA V6. The study underscores the pivotal role of skeleton models in organizing and linking all design information, facilitating efficient interaction between different models. Practical lashing bridge applications illustrate the effectiveness of this methodology. Moreover. the product structure based on skeleton models also embodies the philosophies of top-down and concurrent engineering. This method not only achieves geometric common modeling but also holds promise for broader applications, offering valuable insights for integrated design and serving as a beneficial reference for complex product design methodologies.
