Some Frontiers of Optimization Technology in Research and Application

Abstract

This talk addresses several topics that are highly relevant to today’s trends both in research and in industrial applications.

1. Composite
Utilization of composite material entered a new era around the turn of the new millennium when Boeing and Airbus took the leap of faith towards building essentially full composite airliners B787 and A350. Composite material offers unmatched design and manufacturing flexibility. The increased complexity also presents new challenges for engineering design and manufacturing. To serve broad industrial demand we have developed a comprehensive optimization process for composite laminate structures that leads the design from ply layout concept to detailed ply-book finish. An example of designing a blended composite aircraft wing is illustrated in Fig.1. This talk will highlight several recent advancements: (a) Design of composite for ATL (automatic tape laying) manufacturing; (b) macro feature based fast design realization for F1 Racing industry.

2. Additive Manufacturing
In recent years 3D-Printing, also known as additive manufacturing, has become a broad technology movement. By large its fame is driven by rapidly growing consumer adoption. However, rapid growth has been seen in biomedical applications, and initial successes have also been showcased for aerospace and other fields. 3D-Printing brings almost unlimited freedom for design shape and form, hence offers the perfect combination with topology optimization for creation of most efficient structures. Many successful designs created with topology optimization have been presented in real product environment by leading global companies. We have developed an advanced solution for blended lattice structures (an example is shown in Fig.2). This talk will also highlight recent R&D on topology optimization considering support elimination or penalization; Moving lattice towards meta-material design; Tools for complete process from design to printing.

3. Multi-material topology optimization
As E-mobility is increasingly taking center stage, automotive OEMs are under tremendous challenge for light-weight design to accommodate significant weight increase from the battery pack. Integrating usage of multiple materials have become a trend in electric car design, as shown in the Opel Astra electric car in Fig.3. Hence topology optimization including multiple materials become highly relevant to the industry trend.

4. Fail-safe topology optimization
Failsafe robustness of critical load carrying structures is an important design philosophy for aerospace industry. The basic idea is that a structure should be designed to survive normal loading conditions when partial damage occurred. Such damage is quantified as complete failure of a structural member, or a partial damage of a larger structural part. The author has developed an efficient approach for fail-safe design within the context of topology optimization.
