| The paper aims to propose a CAE idealization method for ship bracket toe structure to improve the efficiency of bracket toe simplification in finite element pre-processing of ship. The 3D octree search algorithm was applied to establish the spatial relationship between 3D bracket toe and nearby ship structures within its surrounding space, and the bracket toes that need to be simplified were filtered and simplified according to the rule of bracket toe simplification. Based on the NX 11.0 platform, the program of bracket toe idealization was developed, which can automatically complete idealization of bracket toe structure. It was tested with real ship models and the result met the quality requirement of finite element meshing. The method proposed in this paper can complete automatic idealization of bracket toe structure with high accuracy and high efficiency. |
