[Objective]In order to improve the efficiency of the finite element geometric modeling of hulls,to address the problem in which hull geometry models exported by ship design software cannot be directly used in finite element modeling,this study propose a geometric model processing method based on the XML file data.[Methods]An Extensible Markup Language(XML)file of a hull exported by AVEVA Marine(AM)software is taken as the research object.First,the data expression rules of the geometric model are clari-fied through the analysis of the data file structure.Then,on the basis of the hull finite element modeling spe-cifications and model data modification,the proposed algorithm can automatically delete and simplify com-ponents such as notches and holes,convert bulb flat and brackets,and move profiles and plate seams.[Results]The processed hull geometry model can be directly imported into finite element software Hyper-Mesh,which complies with the finite element modeling specifications and retains the original model material,plate frame thickness and other related attributes.[Conclusions]Compared with manual modeling,the effi-ciency of testing segmented solid geometric modeling is significantly improved.The proposed method can en-able the reuse of ship design models and improve the efficiency of finite element geometric modeling.
