Abstract: In recent years, with the high-end transformation of the truck industry, the market's requirements for truck lightweight have become one of the important technological breakthrough directions, and the research on aluminum alloy material substitution without changing the original body manufacturing system has become a hot topic. How to more effectively control the cost of trial production and verification, and reduce the initial investment cost and process verification cycle of the mold as much as possible, is the key concern of the lightweight project. Computer aided engineering (CAE) forming analysis technology is used to analyze the forming process of aluminized parts in this paper, and the empirical process plan is revised through the results of virtual verification, and on this basis, the stamping process parameters are fine-tuned in combination with a small range of trial and error verification on the production site, so as to realize the small sheet cost of the aluminized outer plate of a light truck door, that is, the parts that can be used for product test and evaluation are trial-produced. With the application of such methods in the trial production process of door outer panels, it provides a reference experience for the feasibility demonstration of various types of aluminized shallow drawing parts.
