Abstract
The aim of this article was to address the dynamic responses properties and the residual stresses fields induced by laser shock processing (LSP) in a DD6 alloy blade. The dynamic characteristics with [001] and [111] orientations were investigated under different rotor speeds and temperatures by finite element method (FEM) simulation and vibration experiment. As a result, the corresponding static frequencies were analyzed for different temperature, rotor speed and orientation. The residual stresses fields induced by LSP were addressed for [001] orientation at 9800C based on simulation and LSP experiment. Results shown the proposed model was effective. The analyses indicate that the trends of different orders static frequencies were same along [001] and [111], and the orientation had stronger effect on high order static frequencies than it had on low order ones. The best compressive residual stress was achieved to be about 600 MPa when the power density was 4.5 GPa.
