Crashworthiness and lightweight optimization to applied multiple materials and foam-filled front end structure of auto-body

Abstract: Auto-body's front end structure, such as bumper and crash box, has the vital function of protecting other components from damage during low-velocity collision; moreover, it should accomplish excellent lightweight effect under the insurance of crashworthiness. This article combined the two approaches of lightweight improvement that listed as using structural optimization and replacing original materials with high strength and high mass efficiency materials or employing reinforced materials to conduct the crashw… Show more

“…However, stiffness properties are ignored. A good example is the crash management system (CMS) of passenger cars, which is subjected to an impact test [33][34][35][36]. The CMS is a combination of conventional multi-chamber crashboxes and a bumper cross member.…”

“…The Impact attenuators are made in FSAE from various perforated sheets of steel or aluminum alloys [4], [5], hardened or metal foams [5], aluminum or composite honeycombs [2], etc. [7] The usage of each of these materials has its advantages and disadvantages.…”

“…The deformation elements are created by means of various metal crash-box elements [4], [5] and bumpers [5] made of shaped steel sheets in conventional road vehicles. Alternatively, they can be supplemented with various plastic or hardened or metal foams components [5]. However, conventional road vehicles are significantly heavier than the aforementioned FSAE vehicles and are also designed for collisions at higher speeds.…”

“…Few researches considered crash box before and after components in loading process. For example, Li et al 22 used surrogate model to optimize the crashworthiness for functionally graded foam-filled thin-walled structures. They focused the study on structural optimization and material replacements to perform the crashworthiness optimization of the bumper, crash box and rails as an assembly.…”
