| Abstract: | Parts are prone to deformation,which are thin-walled parts,resulting in lower precision of blade.The rule of the blade deformation was found by the analyses of material mechanics and finite element method.A secondary modeling method was presented based on deformation rule of blade.The validity of this method was verified by actual processing. |
