摘　　要：介绍了在板材冲压智能化研究中 ,用坐标网格法分析锥形件成形规律时采用的更精确的数据处理方法 ,给出了各变形质点精确的应变值 (而不是一个小区域内的平均值 ) ,并与以往所用方法得到的结果进行了比较。该方法对更准确地分析锥形件及其它形状零件在冲压成形过程中应力、应变的分布特点及冲压成形机理 。A more precise method of grid data handling was introduced for experimental study of conical part deep drawing as a part of artificial intelligent control of sheet metal forming. The accurate strain values of deformed points were given instead of the average of a small region. The results were compared with those obtained by previous method. It is of great significance for more accurate analysis of strain and stress distributions, discovering the forming mechanism of conical part and other parts, and then for artificial intelligent control of forming process.
