Abstract：
|
|
The rectangular reflector of front lighter on trucks is typical deep drawn pieces with nonaxisymmetric curving shape. The deformation of such part is analyzed in this paper.The blank shape, die radius and blank holder force are optimized by finite element simulation,and the forming quality of the part is improved greatly.
