Abstract:In order to reveal the forming laws,eliminate the forming defects appearing in the typical aluminum alloy web-rib parts,two types of preforms have been used in the final forging with numerical simulation software.Based on the simulation,the comparisons of metal flow,effective strain distribution are obtained between the two types of preforms applied in the final forging process,the forming laws of a symmetrical rib-web component have been obtained ,and the forming mechanism of defects often happened in web- ri… Show more
