Abstract: The instrument panel is the most complex system of automobile interior trim, its design is one of the judgment bases for the success of automobile interior trim development. This paper briefly summarizes two commonly used instrument panels, and focuses on the advantages and disadvantages of different manufacturing processes of soft instrument panels. Due to the large number of matching parts around the instrument panel, this paper focuses on the matching design requirements of the instrument panel with the A-pillar upper trim, front windshield, and front wall sheet metal, so as to provide design reference for subsequent models and increase product competitiveness. Using the commonly finite element simulation software Hypermesh and Abaqus to conduct modal analysis on the instrument panel to verify the rationality of the design and avoid additional mold repair costs due to abnormal noise in the instrument panel area during the subsequent part trial production.
