Abstract：

Sheet hydro-forming is an effective method for manufacturing complicated parts. The manufacturability of hydraulic drawing of cover was analyzed,and the hydraulic drawing process of cover was simulated and analyzed by software Dynaform, and its FLD and thinning rate distribution were obtained. The results show that the maximum thinning rate of cover in the process of hydraulic drawing is about 18.27% and less than 25% by adopting initial designed parameters, and the forming effect is excellent without crack. Thus, the qualified drawing parts are manufactured through hydraulic drawing experiment under the adopted condition in simulation, which verifies the correctness of simulation process.
