Extremum hybrid intelligent-inspired models for accurate predicting mechanical performances of turbine blisk

•Nonlinear dynamic responses of turbine blisk are simulated with FE model.•Six hybrid ANNs with music-inspired optimization methods are proposed.•Training ANN algorithm is proposed to predict turbine blisk capabilities.•These hybrid models are validated by the comparison of different approaches.•Gaussian GHS with ANN holds superior properties compared to other models.
