Objectives  In order to improve the efficiency and quality of fastener design during equipment installation, in combination with the construction design of warships,

  Methods  the design flow of fasteners for warship equipment installation is described. The design function model of fastener design for warship equipment installation was established using the IDEF0 analysis method, and the information transmission and association relation in the design process were analyzed in such aspects as input, output, control and mechanism, accurately reflecting the fastener design process of data flow, information transmission and correlation.

  Results  Finally, based on a design function model acknowledged by both engineers and programmers, a design technology framework was constructed using the VBA language of AutoCAD software.

  Conclusions  The results show that the design function model and technology framework can provide solutions and theoretical support for design engineering application and software development.
