摘要：

针对汽车侧围外板尾灯区域犀利化造型需求和产品结构特点，并制定了产品工艺方案，并创建了CAE分析模型，利用AutoForm软件进行了SE同步仿真模拟分析，结果发现,尾灯造型的犀利化增加了侧围钣金的成形难度，容易产生尖角开裂和拐角圆角起皱问题。分析开裂和起皱问题产生原因，确定拐角处圆角大小、侧壁拔模角度、翻边深度等是导致零件开裂、起皱的主要因素，经过产品多轮优化，最终得出了合理的圆角大小、侧壁拔模角度和翻边深度等工艺参数，解决了开裂和起皱问题，同时满足了犀利化尾灯的造型需求，提升了产品精致性。现场调试出件结果与前期CAE分析一致，大大降低了该零件出现成形缺陷问题的风险。

For the sharp styling requirements and product structure characteristics of taillight area on the automobile side wall outer panel, a product process scheme was formulated. Then, a CAE analysis model was created, and SE synchronous simulation analysis was conducted by software AutoForm. The results show that the sharpness of taillight styling increases the difficulty of forming the side wall sheet metal, which is prone to the problems of sharp angle cracking and fillet wrinkling. The causes of cracking and wrinkling were analyzed, and it is found that the fillet size at the corners, the side wall draft angle and the flanging depth are the main factors that causes cracking and wrinkling of parts. After multiple rounds of product optimization,the reasonable process parameters such as fillet size, side wall draft angle and flanging depth are finally determined to solve the cracking and wrinkling problems. At the same time, it meets the sharp styling requirements of taillight and improves the sophistication of product. The on-site debugging results are consistent with the previous CAE analysis, which significantly reduces the risk of forming defects in the part.
