- Abstract
The purpose of this project was to effectively avoid the defects in the production of the Dongfeng Automobile chassis floor. The research scope was the technological process of the rear floor parts of Dongfeng Automobile. The forming process of the rear floor parts of the Dongfeng Automobile model was analyzed, and the whole process numerical simulation model of the rear floor part was established by using the AutoForm software. The influence of blank holding force, convex concave clearance and drawing speed on the thinning rate and secondary strain of forming parts was analyzed by orthogonal experiment design. The 3 factors, blank holder force, convex concave clearance and drawing speed were analyzed. The optimal combination of edge pressure, convex concave gap and drawing speed were determined by multi-objective optimization. The best parameter combination results: BHF was 1273kN 1.10t mm, the gap between punch and die, drawing speed was 15 mm/ s, the thickness of the parts could meet the requirements of guidance for automotive production, but in mass production, also need to consider in the process of the specific choice of the plate material, the internal organization so, these would affect the process stability. In conclusion, the whole process simulation and orthogonal experiment design could effectively avoid forming defects and determine the forming parameters, and provide guidance for practical production in theory, and provide technical support for the optimization of Dongfeng vehicle floor.
