Abstract：

Compared with other traditional methods, hydroforming technology has obvious advantages in metal forming, but the experiment and simulation on this technology are relatively scarce in domestic. In order to study the regularity of hydroforming, experiment system was designed and implemented, and testing analysis was conducted. The process of the sheet metal hydroforming was simulated by the nonlinear finite element software ABAQUS. The correctness of the simulation analysis was verified based on the comparison of parameters such as minimum radius of curvature. The influences of blank holder force and friction coefficient on forming quality were discussed. The simulation results show that the best value of BHF is between 60-90 MPa for this model, and the influence of friction on forming thickness increases with the decrease of the friction coefficient.
