N2 - On the basis of numerical simulation for the effects of process parameters on the deep drawing of 5A90 Al-Li alloy sheets, the holder force, diameter of blank, punch radius, die corner radius and temperature were optimized by orthogonal experimental design method, and the corresponding deep drawing tests were carried out. The results show that the significance on deep drawing is temperature, diameter of blank, drawing speed and holder force in turn. The optimal making up of deep drawing parameters for 5A90 Al-Li alloy sheets were attained by computing, analyzing and summarizing the results, and the limit drawing coefficient can reach 0.45 under optimal condition.
