关于船体几何模型从 CATIA 到 MSC ．Patran 的转换

摘要

A method is introduced to transfer the geometric model of ship structure from CATIA to MSC .Patran, so as to form the FE model and extract data about properties and group .A model of CATIA for the hull of 300 000 DWT VLCC is trans-fered to MSC.Patran successfully with complete data .It proves that the method is reliable , practicable and suitable for complex plate-beam model of hull structure by practice .%介绍对CATIA几何模型进行规范化处理，利用CATIA CAE划分网格及优化、提取网格属性及分组信息后转换到MSC．Patran中的方法。以1艘30万t超大型油船（ VLCC）舱段结构的CATIA几何模型为例，成功进行转换及计算。验证表明：转换后的信息完整，无需二次加工；该方法可操作性和实用性强，且适用于船体结构复杂的板梁模型。
