Abstract
An integrated system with both Computer Aided Design (CAD) and Computer Aided Engineering (CAE) has been developed. Most of these systems mainly focus on the effectiveness of constructing Finite Element (FE) model In these systems, a FE model is automatically constructed and calculation is automatically carried out. But a good design candidate cannot be obtained since some analysis tools for finding out it effectively are not included. In this paper, firstly some problems in current CAE systems are made clear. Secondly, in order to overcome these problems, two new analyses, that are FOA( First Order Analysis) in a concept design phase and a optimization tool based on a reduction technique in detailed design phase, are presented. Finally, in order to perform these analyses in a integrated system, a few concepts of necessary technique are proposed.
