Abstract: With a car underbody protection panel as the research object, a solid model of the underbody protection panel was established using CATIA software. The finite element analysis software Hyperworks was used to simulate and analyze the static load and impact resistance performance of the car underbody protection panel, evaluate the effects of factors including fixed solutions, reinforcement structure, material selection and etc. The simulation results provide a theoretical basis for the design and material selection of the car underbody protection panel structure.

Key words: Underbody protection panel, Static load, Impact resistance, Finite element analysis
