An Automated Optimization Process for a CAE Driven Product Development

Abstract

Within the product development the need for generating design variants is given in many situations, for example to optimize an existing initial design with respect to new or modified requirements. For an efficient process it is essential that these variations can be done very easily within a small timeframe. In the virtual product development the physical characteristic of a component is determined by numerical simulation. Commercial software products exist for nearly each physical phenomenon. Often these methods are covered under CAE. A fundamental issue for building and analyzing variants easily and fast is a seamless interaction between the CAD and CAE software tools. This paper presents a powerful CAD/CAE sequence to the engineer’s community, where in contrast to other approaches results of the CAE analysis directly interact with CAD data. This strategy is supported by describing the product’s geometry by parameters. The CAD/CAE sequence is integrated in an optimization loop. The presented application example is an automotive part.

A Collaborative Conceptual Aircraft Design Environment for the Design of Small-Scale UAVs in a Multi-University Setting

“…By creating a template for the workflow, various computer-aided engineering (CAE) tools can be attached together and controlled by computer logic. 19 Time-savings and learning from sensitivity analyses by this software are extremely valuable. Sensitivity studies and design explorations run by Optimus are desired features of CCADE planned for future development.…”

Casting Design through Multi-objective Optimization

“…OPTIMIZATION FRAME WORK In virtual product development, the computer aided design (CAD) and analysis sequence is integrated into an optimization strategy, whereby the product's geometry are described by parameters for an efficient process [30][31][32][33].…”

Digital design and manufacturing process comparison for new custom made product family – a case study of a bathroom faucet

“…By being able to answer directly to the customer needs, the market share can be increased, an existing customer base can be maintained or even increased, a better coverage and profit can be achieved and the companies can operate more costeffectively [1][2][3][4]. The European industry has to invest in product development processes and in the designing of high-end and unique products to be able to compete with the low productions costs of the developing economies.…”
