【摘要】 板材成形数值模拟技术和现代优化的集成将大大提高设计质量,缩短产品上市时间。两种方法的结合,必须对板材的成形缺陷进行量化的表示,以形成目标函数和约束条件。为此,本文提出了质量函数的概念,并对起皱、平台区、破裂及回弹等常见缺陷进行了定义。更多还原

【Abstract】 The integration of numerical simulation of sheet metal forming with optimization method will greatly improve the design quality and reduce the time to the market. It is necessary to define a numerical expression of the defects in quantitative measure of the quality of part. So Quality Functions are presented to define wrinkle, flat area, fracture and springback tendency etc.更多还原
