船舶结构有限元模型局部修正方法研究

摘要

In order to achieve the rapid modeling of openings and toes of the ship structure FEM model , the locally refined methods for the finite element model of ship are studied , and the parametric modeling program is developed based on the Patran secondary development platform .The testing results show that the program can quickly and accurately create fine mesh for the openings and toe, so as to alleviate the tedious plan approval surveyor staff duplication and improve the efficiency of plan ap -proval.%为了实现船舶结构有限元模型中开孔和趾端的快速建模，针对有限元网格的局部区域细化方法，基于Patran平台设计开发参数化建模程序。实测证明，该程序能够快速准确地创建开孔和趾端，在一定程度上减轻审图验船人员的繁琐重复劳动，提高审图效率。
