The
method is designed for the technological residual deformations prognostication
of gas turbine components after surface plastic deformation strengthening. This
method is based on finite element analysis and applied for the residual
deformations prognostication of the compressor blade after through-edge of
blade ball rolling strengthening. The finite element model makes it possible to
simulate the effect of strengthening due to shot-peening
of blade and ball rolling of edges of blade. The method may be used for
optimization of the ball rolling strengthening treatment technology.
Key words: compressor blades, strengthening, ball rolling, residual stress, residual
deformation, finite element model analysis.
