Recent advances of sheet metal forming optimization based on meta modeling
Author(s): 
Pages: 20-24,47
Year: Issue:  2
Journal: JOURNAL OF PLASTICITY ENGINEERING

Keyword:  代理模型板料成形数值模拟稳健设计;
Abstract: 综述了板料成形优化技术现状,针对优化中计算成本高的问题,提出了基于代理模型的优化技术,包括可立格模型、响应面模型、神经网络模型等.从实验设计、代理模型的建立,以及优化求解等方面进行了阐述.针对产品设计中因素的随机性和不确定性,为减小目标函数对设计变量的敏感性,将稳健设计理论应用于板料成形优化中,以提高产品的可靠性和稳健性.
