In side vehicle accidents, there is a very short distance between the impactor and the passenger. In such accidents, car manufacturers place impact energy absorber beams inside the door so that the passengers do not suffer from loss of life or major damage. In this study, the crashworthiness performances of impact energy absorber beams were investigated. Comparisons were made by changing the beams’ angles, materials, thickness, and cross-sections. Among the materials used (Aluminum 6061-T6 and A36 steel), Aluminum 6061T6 material stood out with its high Specific Energy Absorption (SEA) value, low reaction force, and low permanent deformation performance. The best Velocity Absorption Time (VAT) value was obtained in the combination where the angle between the two beams defined by A36 steel was 25°. It has been stated that the hexagonal cross-section door beam used is superior to the circular beam and is open to improvement.

“…1 Side impact door intrusion beams used in car bodies are one of the structures that are used to reduce casualties and injuries caused by traffic accidents. 2 These beams are mainly used in the front and rear of the car as a bumper and in the car door as a side impact door intrusion beam. 3 During an accident, the beams used in the body of the car reduce the intensity of the impact caused by the collision by absorbing part of the kinetic energy of the accident, and in this way, a gentler impact is inflicted on the passengers.…”

The bending behavior of beams with a square cross-section containing holes under a three-point bending load was investigated in the present study. As aluminum alloys are lighter than steel and there are many automobile companies that use this material, 6063 aluminum alloy was chosen for this study. The present research was carried out both experimentally and numerically. In the numerical section, aluminum beams were simulated with the finite element software LS-DYNA. These beams contained holes with a diameter of 21 mm, which were placed at different distances on the length of the beam. In this research, 36 perforated beams were simulated in three thicknesses: 1, 1.5, and 2, and the holes were placed at 0, 3.5, 7, 10.5, 14, 17.5, 21, 24.5, 28, 35, 42, and 49 mm in relation to the middle of the beam. In addition, a beam without holes was studied for each thickness. Numerical simulations were validated with experiments and good results were observed. The obtained results showed that as the hole moves from the center to the sides, the absorption of energy and maximum force increases. In the final section, the most optimal beams were determined in terms of thickness and hole location, and based on these a car bumper was proposed.

“…An optimization method was proposed to optimize the B-pillar to improve its side crashworthiness and reduce its SM. More et al [26] studied the cross-section, gauge and material of a side door impact beam. The Taguchi method was applied to optimize the three-point bending performance of the impact beam, and the side crashworthiness of a vehicle model with the optimized impact beam was improved.…”

B-pillar and rocker are the key force transmission sub-systems of the side impact of Battery Electric Vehicle (BEV), and scholars have studied the side crashworthiness of these sub-systems and vehicle body a lot. However, these works are insufficient on the analysis of benchmarking vehicle models, the simulation and experiment of the B-pillar and rocker sub-systems, and the optimization of these sub-systems. To make up these shortcomings, this work aims to design the B-pillar and the rocker, and improve the side crashworthiness of BEV. It presents a systematic method on the side crashworthiness of BEV. The dynamic bending performance of the B-pillar and the rocker are studied in simulation analyses and experiments. The materials, structures and crashworthiness of these two sub-systems of eleven benchmark models are studied. Minimizing structural mass (SM) and Cost as well as maximizing mean crushing force (MCF) are performed based on multi-objective artificial tree (MOAT) algorithm to optimize the B-pillar and the rocker. The optimized sub-systems are applied to the body of a BEV. As a result, the performance of the B-pillar and the rocker is significantly improved, and their optimal solution templates are provided. The performance of the BEV is also improved under the Advanced European Mobile Deformable Barrier (AEMDB) side impact and the oblique pole side impact. Some interesting conclusions for BEV are presented. In summary, this work has obvious reference value for automotive engineers and scholars to further study the crashworthiness and lightweight of BEV.
