- Abstract
The structural elements known as bumper systems, which include beams and face bars, are vital parts of a vehicle's body framework, serving a critical function in dissipating impact energy by undergoing deformation. This research follows to examine and refine the design of frontal member beams within the durable framework of automobiles, specifically focusing on their ability to absorb internal energy generated from frontal collisions while upholding principles of sustainability. By merging conventional techniques in vehicle manufacturing with the innovative approach of "Origami Engineering," commonly employed by entities like NASA and professionals across diverse sectors such as aeronautics, nanotechnology, and medical technology, this study aims to advance our understanding and application of crashworthiness principles. Through the utilization of finite element methods in simulation analyses, diverse configurations including various types of thin-walled metal tubes and structures inspired by Origami were assessed. This interdisciplinary investigation holds promise for enhancing the safety and efficiency of automotive designs, aligning with evolving sustainability objectives. The findings of this research hold significant implications for improving the safety and performance of vehicles in frontal impact situations.
