Abstract：

For automobile sheet metal, a hydroforming experimental system was self-designed and set up, and hollow plate was investigated by experiment in order to study its hydroforming regulation. Then, its hydroforming process was simulated by the finite element software DYNAFORM, and the finite element model and the correctness of the numerical simulation were verified by comparing with the experimental results. Based on above results, the influences of key technological parameters such as blank holder force, loading path of blank holder force, liquid pressure and friction coefficient between plate and die on plate thickness of hydroforming were examined, and the hydroforming process of automobile hollow plate was put forward, which could provide a reference for the application of hydroforming in the forming of automobile parts.
