Abstract: In contemporary society, people pay more and more attention to automobile safety, and the safety crash performance of automobiles has become an important reference basis for customers to buy cars. The front protection beam is a part involving the safety of the whole vehicle, and it is designed to ensure that the collision energy can be fully absorbed during the low-speed collision to ensure the normal function of the electrical components and main components in the front end. Therefore, this paper summarizes the requirements and characteristics of low speed collision, and summarizes the key elements of the design of the front protection beam. Based on the development case of a certain model, the light weight and safety optimization design of the front protection beam is carried out, which also provides a reference for the design of the front protection beam of the subsequent model.

Key words: Safety; Front bumper beam; Low-speed collision; Lightweight
