摘　　要：网格试验在汽车厂冲压生产领域具有重要的指导作用,目前网格试验方法除了传统的手工测量方法以外,随着数字化影像技术的发展,数字化的网格试验方法(DIC)也得到了广泛的应用,通过材料成形极限曲线并结合材料的性能,分析与探讨了冲压缺陷产生原因及改进措施。事实证明DIC网格分析方法可直接反映测量区域变形行为,是进行大型覆盖件冲压成形分析和改进成形缺陷的有效方法。Experimental grid method has an important guiding role in auto stamping production.With the development of digital imaging technology, the digital image correlation（ DIC） grid method also has been widely used in addition to the traditional manual measurement method.Combined with the basis of material test and forming limit analysis,the formation effects of the two parts were evaluated, and the solution were proposed. Results show that the experimental grid method can directly reflect the deformation of the measurement area and it is an effective way to solve the panel stamping problems and quality issues.
