Energy Absorption in Aluminum Extrusions for a Spaceframe Chassis
R. W. Logan, S. A. Perfect, R. D. Parkinson
The paper describes how finite element analysis (FEA) was used to design and verify the crashworthiness of an aluminum spaceframe chassis for a prototype electric vehicle. The work, a collaboration between LLNL and Kaiser Aluminum, focused on optimizing the structure's energy absorption capabilities during frontal and roof crush events. The use of DYNA3D, an FEA code, was critical for evaluating and refining different design iterations and ensuring compliance with safety standards.
