A Modeling Paradigm for Product Specific Design Analysis Integration

Abstract

In spite of recent advancements in computer aided design and engineering (CAD/CAE), such as parametric geometry and automatic mesh generation, a large gap exists between computer based design model and analysis model. In this paper, a new product specific approach to integrate design and analysis integration is proposed. The primary objective of this approach is to capture designer’s intent from the limited interaction with the designer in a language that is familiar to designer and to provide the feed back on the suitability of the design based on the finite element analysis (FEA) so that the design is automatically and iteratively modified. Hence, the proposed modeling paradigm provides capabilities of analysis to the designer and acts as a black box without requiring the designer to possess relevant knowledge of FEA. Priority has been given to the class of problems termed as routine analysis – the regularly used, established analysis model in the product design. A representative case study pertaining to Belleville spring is discussed in the context of the proposed methodology to demonstrate that it enables highly automated routine analysis through FEA for the model.
