Abstract：

Using AutoForm software as analysis platform, the improved plans of surface quality for door outer panel were researched. During the improvement on surface crease of middle or low location for automobile front door outer panel, the actual production conditions were simulated by simulation software, and the defect in actual production was reproduced. The effect of improved plans during simulation was quantized and verified by feed, defect analysis of the process, the uniformity of major strain and zebra line effective etc., and the optimal improved plan was obtained at last. After improvement and affect affirmation, the defect was eliminated, and it agreed with the simulation process. Compared with the traditional method of repairing die directly , the improved method was of high accurate and strong guidance，which shortens the period of repair substantially，reduces the repair cost and improves the die quality.
