Abstract: The interior panel of automotive door is an important component of the automotive interior, and the quality of its design is crucial to the success of vehicle development. This article introduces the common components of the door interior panel, with a focus on the design of the map bag, the installation of the door trim panel, the matching of the inner buckle with the door trim panel, and the design of the speaker cover, providing reference for the design and development of the door interior panel of subsequent vehicle models. At the same time, to verify the rationality of the design, the door interior panel needs to be proven to comply with the design intent through various physical experiments. Finally, the commonly used finite element analysis software HyperMesh and ABAQUS are used to analyze the strength of the door interior panel armrest in the article, and whether its strength value under a vertical load of 220 N is greater than the yield strength of the material. The analysis results show that the design of the door interior panel meets the company's specifications.
