摘要
Abstract
In traditional metamodel-based stamping robust design,due to the errors between meta-model and real model,there were certain design errors in the optimization results.Combining experi-mental design with Kriging model and considering both parametric and metamodel uncertainty,a new robust design method was established herein.The agent models of design parameters and quality index were built,and the Monte Carlo simulation method was combined with genetic optimization algorithm to obtain the optimal process solutions.The results show that compared to the traditional design method,the proposed method can effectively reduce the probability of crack and wrinkle constraint failure,and improve the forming quality and process robustness.关键词
