The bumper beam is an important device to ensure the safety of the car, which can effectively alleviate the force and absorb energy when the car collides. Traditional bumper beams are mostly made of high-strength steel, which has high strength and a low production cost but a heavy weight. With the requirement of being lightweight, high-strength steel is not able to meet the needs of lightweight cars, and composite materials have become the answer to the problem of a light weight in cars due to their excellent performance of being lightweight and high strength. This article introduces the case study on materials of bumper beams and presents the application of traditional materials and composite materials in bumper beams. Then, the fabrications and processes of bumper beams, a performance assessment, experimental tests, and a finite element analysis of the bumper beam are carried out. This paper also represents the study of optimization in automobile bumper beams.
保险杠横梁是确保汽车安全的重要装置，在汽车碰撞时能有效缓冲力量并吸收能量。传统的保险杠横梁大多由高强度钢制成，其强度高、生产成本低，但重量较大。随着轻量化要求的提出，高强度钢无法满足轻量化汽车的需求，而复合材料因其优异的轻量化和高强度性能，成为解决汽车轻量化问题的答案。本文介绍了保险杠横梁材料的案例研究，并阐述了传统材料和复合材料在保险杠横梁中的应用。然后，对保险杠横梁进行了制造工艺、性能评估、实验测试以及有限元分析。本文还介绍了汽车保险杠横梁的优化研究。
