GOALI/IUCP: Process Modeling and Optimization for Crashworthiness of Extruded Aluminum Components

燃油效率和车辆耐撞性是现代汽车制造的两个重要问题。目前的行业标准要求铝结构部件吸收足够的碰撞能量，同时将材料微裂纹限制在亚临界断裂。因此，成功的抗碰撞铝部件设计必须考虑材料的微观结构特性、详细的材料失效机理以及决定这些特性的产品和工艺参数。该研究项目是该大学与一家工业合作伙伴共同开展的一项研究工作，旨在开发改进的制造工艺，以生产具有优异性能的汽车耐撞性挤压铝部件。这一合作研究项目在理论和实验之间取得了平衡，将为汽车制造和铝制造行业提供有价值的研究成果。

Fuel efficiency and vehicle crashworthiness are two important issues for modern automotive manufacturing. Current industry standards require aluminum structural components to absorb sufficient crash energy while limiting material microcracking to subcritical fractures. Thus, a successful design for crash-resistant aluminum components must consider microstructural material properties, detailed material failure mechanisms as well as the product and process parameters that determine them. This research projects is a joint research effort between the University and an industrial partner to develop improved manufacturing processes for the production of extruded aluminum components with superior properties for automotive crashworthiness. This collaborative research project has a balance between theory and experiment, and will provide valuable findings for the automotive manufacturing and aluminum manufacturing industries.
