Abstract

Automotive bumper beams play a very crucial role in absorbing impact energy during crash collisions and reducing damage from the front or rear ends of the vehicle during low or high-velocity impact. This paper discusses the impact of different energy-absorbing materials introduced between the fascia and the metallic beam. A novel recipe, with combinations ranging from 0% to 50% and 20% to 80% of Polypropylene (PP) with Ethylene vinyl acetate (EVA) and Polypropylene (PP) with Ethylene propylene diene monomer (EPDM), was prepared by weight and comparative study based on their impact strengths was done both experimentally and numerically. The mechanical properties of the polymer blends have been determined under tensile, compressive, and impact testing. Results obtained from numerical simulation analysis lie in reasonable agreement with the experimental findings. The tensile and compression test results show that polymer blend PP/EPDM-50/50 is the best selection as an energy absorber due to its ductility and toughness properties which is evident from experimental testing. The introduction of this blend in front of the metallic strip (bumper beam) has significantly supported the improvement in the energy-absorbing capacity and impact strength.

分析不同速度条件下阻尼材料对汽车保险杠横梁总成的影响
汽车保险杠横梁在碰撞过程中吸收撞击能量、减少低速或高速撞击对车头或车尾造成的损坏方面发挥着非常关键的作用。本文讨论了在饰板和金属横梁之间引入不同吸能材料的影响。本文按重量制备了一种新配方,其中聚丙烯(PP)与乙烯-醋酸乙烯(EVA)和聚丙烯(PP)与三元乙丙橡胶(EPDM)的混合比例分别为 0% 至 50% 和 20% 至 80%,并根据其冲击强度进行了实验和数值比较研究。在拉伸、压缩和冲击试验中测定了聚合物混合物的机械性能。数值模拟分析得出的结果与实验结果基本一致。拉伸和压缩测试结果表明,PP/EPDM-50/50 聚合物混合物因其延展性和韧性而成为能量吸收器的最佳选择,这一点在实验测试中也得到了证明。在金属带(保险杠横梁)前引入这种混合物,对提高能量吸收能力和冲击强度有很大帮助。
