摘要: 將相似理論與正交試驗設計引入計算機仿真方案的制定中,并使用大型通用非線性有限元軟件MARC/AutoForge對異徑四通管的液壓脹形工藝過程進行了仿真.得到了最佳工藝參數.Abstract: Similar theory and orthgonal experiment method are applied to the computer simulation. The liquid bulge forming process of a four-arm tube is analyzed by using the non-linear finite element program, MARC/AutoForge. The computer simulation result gives the effects of main process parameters during the forming process and the optimal process parameters such as balance force, friction, radius of round angle, and rate of velocityare obtained.
