Integrative Technology for Three-Dimensional Structure CAD and CAE of Port Wharf Based on Template

针对港口码头结构CAD几何模型生成CAE单元模型,工程荷载CAD模型创建CAE荷载模型,和CAE分析结果与CAD模型的关联关系等问题,利用模板的模型独立性、规则性和可执行性等特性,研究了基于模板的港口码头三维结构CAD/CAE集成技术,定义了截面草图、三维实体和构件等多种CAD建模模板,定义了机械草图和荷载等多种荷载建模模板,定义了CAE分析规则,实现了CAD几何模型自动生成CAE单元模型的功能,定义了荷载转换规则,实现了工程荷载CAD模型自动创建CAE荷载模型的功能,定义了整体模型模板,建立CAE分析结果与CAD模型的多对一关系,以此实现了港口码头三维结构CAD/CAE集成系统,大大提高了港口码头的设计效率,降低了设计人员的设计难度,减少了设计错误。

Aiming at integrative problems of three-dimensional structure CAD and CAE in port wharf, the paper studies the integration technology of three-dimensional structural CAD and CAE based on the template characteristics of model independence, rules, execution etc.. It defines section sketch template, three-dimensional entity template, component template and other CAD modeling template, while defines mechanical sketch template, load template and other load modeling template. It defines CAE analysis rules for automatically converting CAD geometry model to CAE unit model, defines load conversion rules for automatically converting engineering load CAD model to CAE load model, defines model template for establishing the relationship of CAE analysis results and CAD model. It implementes the integrated system of port wharf three-dimensional structure CAD and CAE to greatly improve the design efficiency of port wharf, reduce the design difficulty and errors.
