Deformation measurement and simulation of Ti–6Al–4V blades induced by shot peening process

One factor that plays an important role in the aerodynamic performance of aeroengines is shape blades, which vulnerable to change resulting from plastic deformation and residual stresses induced by complex manufacturing processes, especially shot peening. However, few studies were focused on detailed strategies peening profile superposition effects during entire processes. In this paper, based concept eigenstrains, we investigated effect blade combining experimental measurement local-global simulation. The results show initial previous milling process could be neglected. After peening, has largest if considering with large amount material removal, compared case without after dynamic blades. Furthermore, in-out sequence smallest pre-deformation can effectively offset deformation. Finally, intensity should not too high practical for small thickness order avoid compromising reliability safety
