Diagnostics of Turbine Blades, Based on Estimation of Frequency Response Function

Diagnostics of Turbine Blades, Based on Estimation of Frequency Response Function

The aim of the study is to propose a diagnostics method based on blade’s vibration model in frequency domain. Amplitude spectrum A(ω) and phase spectrum φ(ω) have been experimentally identified which define transfer function G(jω) = P(ω) + jQ(ω) and their real P(ω) and imaginary Q(ω) parts. Transfer...
