Abstract：

Tailor Rolled Blank(TRB) shows enormous potential in the aspect of automobile lightweight. In order to promote the application of TRB in the field of auto parts manufacturing, the formability of TRB was studied by experiment and simulation for the box part, and the influences of geometric parameters of TRB on formability were analyzed. Furthermore, the relationship between geometric parameters and forming limit as well as thickness thinning ratio for TRB box part during drawing process was discussed respectively. The research results indicate that the geometric parameters greatly affect the formability of TRB. The formability of TRB is in inverse proportion to ratio of the thinner side, blank thickness difference and blank size, and is in proportion to thickness transition zone length. Thickness transition zone is offset to the thinner side, the larger length of transition zone, the smaller blank thickness difference and blank size are preferable for acquiring better formability of TRB.
