【Abstract】 To the process of sheet metal forming, there are many boundary conditions to influence forming, such as draw bead, draw threshold, lubrication condition etc. An optimization of the process parameters of oil pan forming was done. The effects of the shape and size of blank, the position of blank, the blank holding force and the draw bead to the forming process were studied and the reasonable results were given. An approach of applying CAE technology to the process design of sheet metal forming was proposed.更多还原
