Numerical simulation of deforming manufacturing process for aero-engine annular blanks
Ring rolling technology is widely used to produce the aero-engine annular blanks, yet the geometry of the aero-engine annular blanks are often complex, and thus result in a high material waste ratio when producing by the traditional trail-and-error method. A three dimensional simulation model of the RAW200/160-5 radial axial ring rolling machine was firstly created based on the general dynamic explicit finite element code ANSYS/LSDYNA, and then realized the virtual simulation of the entire rolling process of the turbine case blank within a producing cycle, at last gave out the results of the state graph, stress and strain contours of the blank. These simulation results reflect the ring expanding and fleck generating process of the simulation, which agrees the real rolling process and thus verifies that this numerical simulation is feasible to guide the produce of aero-engine annular blanks, reduce cost and improve efficiency.
