The Research on Integrated Computer Aided Engineering system for Shipbuilding

本研究的目的是通过将设计系统和生成产品信息的分析系统整合起来，实现信息的顺畅传递。指出设计系统和产生产品信息的分析系统应集成。本研究的目的是开发使信息传递顺畅的集成购买方法。此时，研究了关注集成管理产品信息的"产品模型"，以及支持产品模型生成和CAE的产品定义系统，以使产品模型集成为核心。本研究取得的成果如下。(1)初步设计支持系统的开发为了支持船舶初步设计中的纵倾计算、稳性计算等，分析系统 ...更多信息 实施了有效利用研究代表提出的产品模型信息的TEM。(2)结构分析支持系统的开发与集成为了支持船体结构的结构分析，构建了有效利用产品模型信息的结构分析支持系统。使用被定义为产品型号、板厚、材料等信息的结构构件的形状信息的属性信息，通过有限元法分析自动生成必要的有限元数据，开发了支持设计人员提高信息制作效率的系统。(3)提出了易于集成的系统框架和原型系统的开发我们考虑了系统的基本组成部分，其中两个或两个以上的分析系统似乎是有效的，主要是产品模型集成。因此，我们判断，我们必须检查的机制，通过该形式，系统集成对应的目的是实现编程和机制，一个灵活的行动，与另一个分析系统集成的问题，可以完全完成。然后，对系统的制作思想、对组合环境的集成制作技术和部件维护技术进行了有效的研究。因此，我们能够实现原型系统，能够灵活地集成多个CAE系统。少

This research is for the methodology of integration by which the information transmission is smoothly enabled by thinking that the design system and the analysis system which generates product information should be made integrated. It is pointed out that the design system and the analysis system which generates product information should be made integrated. The purpose of this research is development of the methodology of making to integration buy which the information transmission is smoothly enabled. At this time, it was examined to pay attention to "Product model" by which product information was managed integrated, and for product definition system which supported the generation of the product model and CAE to make the product model integrated as a kernel. The result achieved for this research is shown as follows.(1) Development of elementary design support systemTo support the trim calculation and the stability calculation etc. of the ship in an elementary design, the analysis sys … More tem which effectively used information on the product model which the research representatives were proposing was implemented.(2) Development and Integration of structural analysis support systemTo support structural analysis of the hull structure, the structural analysis support system, which effectively used information on the product model, was constructed. A necessary finite element data was generated with the finite element method analysis automatically using attribute information on shape information on the structural member defined as information on the product model, plate thickness, and the material, etc., and the system which supported the efficiency improvement of designer's information making was developed.(3) Proposal of framework of system of easy integration and development of prototype systemWe considered the basic component of the system from which two or more analysis systems seemed to be effective to make mainly the product model integrated. As a result, we judged that we had to examine the mechanism that the form by which system integration corresponding to the purpose was achieved programming and the mechanism that a flexible action on the problem of integration with another analysis system could be done completely. Then, making of the system thought that we were effective to the technique of making to integration and parts maintenance of the combination environment were examined. As a result, we were able to implement the prototype system that was able to integrate several CAE systems flexibly. Less
