Optimization of structural components

Researchers present a new design methodology to develop structural components using computer-aided engineering tools.

The theory and practice of topological optimization has been continually refined, and various in-house and commercially available computer programs have been developed for the topological and shape optimization of structural components. Numerous studies have described weight-reduction optimization or stress-leveling optimization of previously existing components, but not much information has been available that uses the computer-aided-analysis optimization process as an initial design technique.

Researchers from Dana Corp. have found ways to improve and expand on the application of topological- and shape-optimization computer analysis techniques for the design of new structural components, particularly early in the design process. The proposed methodology relies on computer-aided topological- and shape-optimization procedures for arriving at the load paths in the component and for optimal distribution of the material at the beginning and end of the design process.
