CAE解析手順の標準化手法の開発

抄録

In order to shorten design period, CAE analysis using 3D-CAD is required to evaluate design results before prototyping. However, designers cannot often use CAE analysis to do a lot of design work. Therefore, knowledge of analysis procedure and analysis know-how from designers is difficult to accumulate. On the other hand, analysis working efficiency has to be improved because CAE analysis working hours for designers are limited. Many studies have been achieved for supporting CAE analysis of designers. Most of them are automation technique of CAE model generation. This paper focused on CAE analysis procedure to improve analysis efficiency. We have developed a CAE analysis procedure standardized method. We applied this technique for thermal analysis. The standardized thermal analysis procedure consists of eight procedures, namely, extraction of analysis object parts from assembly, unit setup, material setup, model simplification, mesh generation, boundary condition setup, calculation execution, and visualization of results. We demonstrated that thermal analysis work time is shortened maximum 50 % by using CAE analysis procedure standardized method. Evaluation result of persons experienced and inexperienced in analysis showed that the procedures of model simplification and boundary condition setup are important.
