Abstract：

In order to study the influence laws of geometric parameters for cross ribs on the forming quality problems of rib insufficient filling, folding and so on during the hot orbital forming process of aluminum alloy cylindrical part with cross ribs, taking the width and height of cross ribs as variables, the experimental design was carried out by Box-Behnke designing(BBD) method, and the hot orbital forming process of cylindrical parts with different rib widths and rib heights was simulated by the finite element method. Then, the filling quality and folding rate of ribs with different rib widths and rib heights at the end of forming were calculated, and taking the width and height of cross ribs as the design variables and the filling quality and folding rate of ribs as the objectives, a quadratic polynomial response surface model (RSM) was established. Furthermore, the forming quality of part with different rib width and rib heights was obtained by combining response surface model and finite element method, and the height and width of cross rib when the forming quality was the best were predicted, which were simulated and verified by finite element. The results show that the filling quality of ribs is better when the height-width ratio of high ribs is less than six, and the folding rate decreases gradually with the increasing of the rib width. After optimization, the ribs of part are filled fully, the fold defects are few, and the simulation results are consistent with the prediction results to verify the accuracy of the response surface model.
