Abstract:
New double rollers clamping expanding spinning process was adopted to manufacture the fan casing,and using FE simulation code ABAQUS/Explicit,the 3D simulation model of expanding spinning process for fan casing was built,and the spinning process and material deformation were simulated.Distribution of equivalent stress,equivalent strain and wall thickness of fan casing were obtained.And then effects of roller feed rate on the stress,strain and wall thickness difference of formed fan casing were studied.Results show that equivalent stress and equivalent strain decrease with the increase of roller feed rate,while maximum wall thickness difference increases with the increase of roller feed rate.Comprehensive consideration suggests that the value of roller feed rate should be 0.16 rad·r-1.
