Dynamic model updating of an aero-engine casing

  • Dynamic model updating technique was applied to update a finite element(FE) model of an aero-engine casing.The modal data obtained from conducting vibration modal test to the casing were used as a reference to update the FE model.Based on the sensitivity of frequencies with respect to the element stiffness,some regions to be adjusted were selected.Then,model updating of the aero-engine casing was conducted using a first-order optimization method.The result shows that prediction of the first 10 modes from the updated FE model of the aero-engine casing and that from the measured ones were within 2%,therefore,it is feasible to apply the model to the whole engine dynamic analysis.
