Direct multi-objective optimization of parametric geometrical models stored in PLM systems to improve functional product design

Abstract

This paper presents a functional analysis and design method, including an optimization loop, which has been integrated into our self-developed, web-based Product Lifecycle Management (PLM) platform. Our design methodology, which includes advanced and parametric CAD modelling and direct multi-objective optimization is described here. Functional design and knowledge-based engineering features, such as functional parameters, expert rule definitions and design experience feedback are all developed in the product design process in order to reduce costs, lead time and also to improve product quality and value. To confirm our research hypotheses, an experimental case-study is chosen: the ground-link system of a racing car design and manufacturing project, including conceptual, embodiment, detailed design and manufacturing phases.
