摘要	The process of automobile lightweight can be promoted by the application of tailor rolled blank (TRB) in the automobile industry. Therefore, research on the formability of TRB is of good practical significance and application value because of the enormous potential of TRB in the aspect of automobile lightweight. Aiming at the present condition of lack of researches on the influence of characteristic parameters on TRB drawing process, the drawing formability of TRB was studied with a combination method of simulation and experiment by taking square box as the research object. Firstly, drawing simulation and experiment of TRB were carried out. Then, effects of thickness transition zone (TTZ) position and blank size on the drawing formability of TRB were analyzed. Forming limit and TTZ movement for TRB square box during the drawing process were respectively discussed, when transition zones of TRB were located at different positions and blanks were of different sizes. The results indicate that lubrication condition exerts greater influence on TRB forming limit in comparison with TTZ movement, and the smaller blank size and TTZ being located at the blank center or slightly offset to the thinner side are preferable for acquiring greater forming limit and smaller TTZ movement.
