Notes:
The advent of high-strength and high-precision thin-walled parts with inner ribs adapts tothe increasing demand of aerospace industry, astronautics industry, military industry, and so on. For anew metal forming technology, how to determine the reasonable blank is a key problem requiredsolved firstly in the research of power spinning process of parts with transverse inner rib. In this paper,based on the platform ABAQUS/Explicit, a reasonable 3D FE model for power spinning of parts withtransverse inner rib has been established, the power spinning process of parts with transverse inner ribhas been simulated under conditions of four typical blanks and the reasonable blanks for differentforming processes have been obtained. The results show the following:(1) Blank with equal half-coneangle is the best selection to deform workpiece with proper height rib; (2) while for the workpiecewith excessive height rib which exceed the forming limit, blank with rib is the exclusive selection,although it is difficult to be prepared comparing with non-rib blank
