Description
Most vehicle bumper systems are traditionally made of materials such as steel or aluminum. While these materials are suitable for absorbing impacts, they carry significant weight. Advancements in materials science have made alternatives such as composites more accessible and practical, and these materials can be implemented into the bumper subsystem of an electric vehicle to reduce vehicle weight while maintaining or improving the crashworthiness of the vehicle. Furthermore, electric vehicles do not possess an internal combustion engine, which helps to manage the energy absorbed during a collision. This means the geometry of the crash structure plays a vital role in occupant safety and effectively absorbing collision energy in a controlled manner. This research focuses on the numerical modelling of these collisions using finite element software to determine the effectiveness of lightweight honeycomb geometry. The end goal is to maximize deformation energy while minimizing peak forces and acceleration on occupants as well as optimizing the weight of the structure.
