For a large aluminum-alloy aircraft forging,a local loading was proposed to solve the problem of the excessive loading during the integral deforming. Then,the filling and loading,the multi-pass deforming assignment and the loading order for the local loading were studied by the finite elements method. The results show that when the aluminum-alloy forging is loaded integrate,the maximum deforming load 400 MN in integral forming is over the load provided by the existing equipment. While 3-segment 2-pass defor...
