Analysis on Residual Stresses of the Casing Part in Aeroengine Based on Hole-Drilling Method

Abstract:

In order to study the residual stress distribution of the casing part in aeroengine, the hole-drilling method was used to measure the residual stress before and after the annealing treatment. The measurement results indicated that the annealing treatment significantly improved the residual stress distribution in the part, and the residual stresses were showed as compressive stress. Meanwhile, the measured residual stress distribution would provide the basis for controlling the machining distortion of the casing part in aeroengine.
