摘要
[目的]船舶设计单位和检验单位通常使用不同的三维设计软件平台,导致出现模型传输不通畅、数据无法有效转换的问题。为此,开展面向送审的船体结构三维模型转化数据技术研究。[方法]通过对CAD和CAE系统模型数据进行分析,给出面向送审的船体结构三维模型数据,介绍数据存储格式与常见三维软件平台接口的设计方法。以某船舱段模型的数据为例,采用XML文件实现三维模型数据存储,并且基于CATIA和Patran软件进行二次开发,重构舱段设计模型,生成有限元分析模型。[结果]所生成的模型已经提交法国船级社(BV),用于直接对该舱段的结构设计进行检验。[结论]提出的送审数据转化技术方案,能够简化不同平台的模型转换,可为实现无纸化船舶三维模型送退审提供参考。
[Objectives]Chinese ship design and approval institutions usually use different 3D design plat-forms,which can cause the problems of unsmooth model transfer and ineffective data conversion.This paper addresses the data conversion techniques of 3D ship structure models to ascertain whether a converted model can be directly used by classification societies for approval.[Methods]By analyzing the model data of the CAD and CAE systems,the required data for generating an approval-oriented 3D hull structure model is sum-marized.The storage format of the required data and the interface between the stored data and common 3D software platforms are introduced.Taking a cargo tank section of a ship as an example,the required data of the 3D model of the target section is stored in an XML data file.Based on this data file,the design model and FE analysis model of the target section are reconstructed through CATIA and Patran software,and equipped with a secondary developed interface.[Results]The reconstructed model has been submitted to Bureau Veritas(BV)for direct approval of the structural design.[Conclusions]The data conversion method proposed in this paper simplifies model transfer among different platforms,and can provide valuable references for realiz-ing the paper-free approval of 3D ship models.
