Dynamic parametric modeling-based model updating strategy of aeroengine casings

•Propose parametric modeling-based model updating strategy (PM-MUS) for structural dynamic modeling and updating.•Deal with uncorrelated mode shapes by introducing an objective function.•The proposed model updating method can correctly identify CMPs in dynamic model updating.•Finish accurately FE mo...
