Abstract: As a common means of transportation in daily life, cars require more storage space. The rolling shutter door storage is a common structure of the interior trim, it adds a sense of grade to the car interior. This paper briefly introduces two common surface treatment processes of it, discusses some design points in the design process for two different rolling shutter door storage , and gives the corresponding physical experiment standards of rolling shutter door storage, in order to formulate corresponding standards for the design and development of it, so as to provide corresponding reference for the design and development of the corresponding structure of subsequent models. At the same time, in the design stage, in order to verify the rationality of the design of the rolling shutter door storage, the stiffness analysis is carried out through the finite element analysis software HyperMesh and ABAQUS, combined with the enterprise's analysis standards and qualified basis. The analysis results show that the stiffness of the rolling shutter door storage designed with reference to the design points meets the requirements of the design specifications, avoid the mold modify cost caused by insufficient rigidity of produced products.
