Ship structural strength verification software design for inland ships based on structure and parameter abstract model

  Objectives  This paper aims to propose a type of structural verification software for inland ships with embedded specifications, addressing the problem of low calculation efficiency and difficult model reuse in performing manual checking and calculation.

  Methods  The software is constructted based on the model-view-controller (MVC) framework, with the hull model as the center and the development of core functional modules such as the structural database, section visualization and specification calculation. A hierarchical model of the structure is designed for parameter management and sharing; the model is abstracted to express special structures and decouple from the specifications; and derivation technology is integrated to facilitate software update and model reuse.

  Results  The calculation example shows that this verification software based on the abstraction of structural parameters can ensure the integrity and accuracy of specification calculation, and realize the complete compatibility and combination verification of various inland ship types and specifications, with an error rate of just 0.1% against the manual calculation results.

  Conclusions  The proposed software breaks through the limitations of different ship types and specifications, realizes intelligent and dynamic structural verification, and reduces the dependence of users on complicated rules and regulations. As such, it can significantly improve the quality and efficiency of design and planning approval work. Compared with other standard structural checking software, this software has the advantages of accurate calculation and rapid modeling.
