Abstract: The contrary to forming features of the cross section of U type parts of sheet metal, we used numerical software DYNAFORM to research its forming technology. By setting up finite element analysis model,forming process of the cross section of U type parts were simulated. According to the simulation results,we analyzed and observed the situation of forming part,unit area of a typical stress-strain states were also analyzed. Contrary to forming defects,reasonable optimization measures were proposed,and the effects were simulated,the wall thickness reduction rate has decreased from 30% to below 20%,which could provide reference for the actual production and application.
