TITLELight-weighting Transportation to Reduce Emissions using Additive Manufacturing

ABSTRACTThe transportation sector is the largest source of CO2 emissions in the United States, and reducing these emissions to meet climate targets will require the adoption of energy-efficiency technologies such as light-weight materials in addition to low-carbon energy sources. Additive manufacturing (AM) has the potential to enable light-weighting across a wide range of the transportation sector, but new design for AM (DFAM) computational tools are needed to reoptimize vehicle systems for AM and reduce production costs before it will become widespread. This talk will discuss computational DFAM methods for parts consolidation and redesign of vehicle systems. We have developed topological optimization methods that minimize AM production costs and system weight subject to structural requirements during the system's use. The method determines how to consolidate parts in the system and redesign the geometry of these parts, optimizing tradeoffs between build time, assembly steps, and material use and support structure requirements, which can increase production costs and environmental impacts. The talk will conclude with design strategies and materials innovations that could enable light-weighting transportation systems while reducing the upstream embodied energy of materials in the system.
