Study on Parameters' Optimization Design of Automotive Panel Sheet Forming Using Kriging Metamodeling Techniques
摘要
Abstract
A sample data design was carried out by adopting Latin square experimental design method.In order to improve computing efficiency,a Kriging surrogate model was introduced into the complex system of optimization design of automotive panel sheet forming,and was employed for producing coarsen response surface.And then,the Kriging interpolation method was used for constructing the better robust surface to decide the better initial values of design variable and reduce constraints to in considerable range.Finally,genetic algorithm was applied for finding the best optimization results.The optimization results show which is able to accurately quantify the warpage of sheet metal forming and crack in the trends and characteristics,Kriging-based optimization method is done,and Kriging model has better prediction ability,with the accuracy of the interest region and the points with larger predicted uncertainty for the accuracy and efficiency of the global approximation.It is optimized by suggested method on the holder force,drawbead resistance of automotive panel sheet forming to eliminate the crack and wrinkle,with good results.关键词
