摘要: A method for determining the resonant frequency of vibration a rotating blade comprises approximate resonance and at plurality frequencies in range above below frequency. At each two measurements are taken representative synchronous amplitudes measurement point (P 1 P 2 ) wherein points separated by an angle β there unknown number x complete vibrations between points. set data is provided plot produced, being analysed to determine likely value hence
