Abstract：

In order to effectively form forgings with high and narrow ribs, three different blank structures were proposed which were simulated by finite element software Deform 3D and verified respectively by experiments. The results show that the height of blank should be close to the height of forgings for the forming of forgings with high and narrow ribs, which can effectively form the target forgings and avoid the forging defects, and the mechanical property test of forgings under the optimized process was conducted. The results show that the mechanical properties of forgings for different batches are consistent. Comparing the simulation results with the experimental results, it is found that the defects produced during the forging process can be simulated accurately by finite element simulation software, which can effectively shorten the time of process development and reduce the cost of trial and error. Thus, the blank design proposed has a certain universality, which has reference significance for the formulation of the forging process for the same type of forgings.
