Composite skin being manufactured over a solid metallic core.
This project focuses on the development of a computational system and educational materials for optimizing the design of 3D core structures produced by additive manufacturing (AM).
The complexity of aerospace tooling structures (scaffolds) and their geometric envelopes, combined with the subsequent fabrication (skinning) and in-use loads experienced, makes optimizing the design and fabrication of core structures a challenging task.
The objective outcomes of this project are:
- A new technology for weight-optimal core structure design for additive manufacturing (AM);
- Algorithms to translate optimized core structures in the form of voxel images into 3D parametric models for universal applicability and dissemination; and
- CAD software and User Interface (UI) that implement these algorithms and plug-ins for existing CAD software.
Develop a computational system and educational materials for the optimal design and AM of 3D core structures central to the aerospace industry.
Develop advanced solutions using finite element methods, non-linear high-dimensional optimization, and Design for AM (DfAM).
Apply technology to functional components provided by Automated Dynamics (AD), Aurora Flight Sciences, and United Technologies Research Center (UTRC). Once the technology validation is complete, it will be incorporated into Siemens’ NXOpen API platform for wide scale dissemination.
