Abstract
To remain competitive in the globalized world, Small and Medium Enterprises (SMEs) need to create and design structures that are cost-effective and consistent with specific mechanical performance. In this paper, we are interested in the economical impact of numerical optimization and the necessity to define a new management of the design process. The linear process of design-engineering-manufacturing is nowadays obsolete. Even DFX (Design For X) methodologies are often replaced by Simulation for XFD (X being also Design) approaches. Optimization is also often applied before design. For instance, engineering design optimization of mechanical structures is nowadays essential in the mechanical industry (automotive, aeronautics ...), but optimizing mechanical structures cannot be efficient without taking in account other phases of the design-manufacturing process. In some cases, optimization is only based on trade knowledge. Engineers must design parts or assemblies that are a better compromise, between mechanical and functional performance, weight and manufacturing costs, etc. This paper gives a brief overview on different disciplines in design optimization of mechanical structures through an "automatic" approach. We propose a new methodology to integrate numerical optimization in a functional design process, which can achieve huge economical gains as demonstrated by two industrial examples in this paper.
