Forced-Response Analysis and Machine-Learning-Based Prediction of Aero-Engine Fan Blades Using the Harmonic Balance Method

This study combines harmonic-balance simulations, modal response analysis, strain-gauge measurements, and machine-learning regression to assess the forced response of a three-row axial fan. At 10,500 rpm, Campbell-diagram analysis identifies a near-resonant third-mode rotor respo...
