Abstract: Bumpers are important exterior components of automobiles, and their design determines the success of the developed vehicle model in a certain way. This paper focuses on the package requirements of car bumpers during the development process, such as position package requirements, pedestrian protection requirements, vehicle performance requirements, bumper layout regulations, and matching requirements between the front bumper and fog lights. It can provide corresponding reference for the analysis of human-machine layout of car bumpers. At the same time, finite element analysis software HyperMesh and ABAQUS are used to analyze the stiffness of the front bumper. When a force of 98 N is applied to the bumper, its deformation is not allowed to exceed 10 mm. The analysis results indicate that the deformation of the front bumper under the corresponding load is 2.435 mm, which verifies that the previous bumper design meets the requirements and avoids mold repair costs caused by improper design of the front bumper in the future.
