Abstract

The invention discloses a CAD (computer-aided design) / CAE (computer-aided engineering) integration method and a CAD / CAE integration system for a steel support structure of a nuclear power plant. The CAD / CAE integration system comprises a CAD system, a CAD / CAE integration tool and a CAE system, wherein the CAD system is used for generating a CAD model of a steel support structure, the CAD / CAE integration tool is used for searching CAD model data and converting the CAD model data into a command stream recognized by the CAE system, and the CAE system is used for receiving the command stream, reconstructing a CAE finite element model of the steel support structure according to the command stream and outputting the CAE finite element model. The CAD / CAE integration method and the CAD / CAE integration system have the advantages that the method and the system are capable of performing topological transformation on the CAD model by extracting key characteristic information in the CAD model, automatically generating a data format recognizable by CAE software and reconstructing the finite element model in the CAE software quickly finally; the CAD / CAE integration tool of the steel support structure is developed by the PML, so that zero-distortion conversion of the CAD / CAE model is achieved truly.

Description

technical field [0001] The invention relates to the field of nuclear power engineering design, in particular to a CAD / CAE integration method and system for a supporting steel structure of a nuclear power plant. Background technique [0002] CAD (Computer Aided Design, Computer Aided Design) and CAE (Computer Aided Engineering, Computer Aided Engineering) software are indispensable auxiliary tools in nuclear power project engineering with digital technology as the core. CAD software is used for product design, and CAE software is used for analysis and simulation optimization of product performance. In the design process of nuclear power products, it is necessary to conduct finite element analysis on the CAD model established by the design professional to verify its mechanical properties. In order to avoid remodeling in CAE software, the traditional CAD / CAE integration method is to directly import the CAD model into the CAE software. However, the use of this traditional CAD / ...
