Significance Analysis on Springback Infecting Factors in Rubber Bladder Forming Based on Design of Experiment and Grey Relation Degree
摘要
Abstract
Rubber bladder forming is a kind of important forming process for aircraft sheet metal springback infecting factors might control the springback effectively.Herein,orthogonal experimental design combined with grey relation degree was used to analyse the significance for rubber forming springback influence factors based on the finite element numerical simulation,and a practical long straight Ushaped part was taken for example to analyse the influence degree on springback of these factors such as pressure,maximum volume flow rate,maximum node rate,holding time,bending radiG us,sheet thickness and the rolling direction.The analysis results show that bending radius of die,presG sure,sheet thickness,holding time are the main influence factors for rubber forming springback,and other factors have less effects.The analysis results are consistent with the experimental ones,so the efG fectiveness of this method can be validated.关键词
