Abstract：

In order to solve the problems of crack, wrinkle and transition zone movement for tailor rolled blank (TRB) in the process of deep drawing, TRB parts were manufactured by hydro deep drawing(HDD) process. Then, the formability of TRB in HDD was studied by numerical simulation, and the HDD process of TRB box part was simulated. Furthermore, HDD was compared with traditional drawing, and the influences of liquid pressure on the formability of TRB were discussed. The results show that the formability of TRB can be improved by the application of HDD. As the liquid pressure increases, the thickness thinning decreases first and then increases, and the thickness transition zone movement decreases. TRB with larger size is more sensitive to the variation of liquid pressure than that with smaller size. However, proper liquid pressure can be selected to acquire TRB parts with high quality for the blank with any size.
