Abstract

Considering that the highest resolving frequncy in dynamic data is restricted by sampling ratio,a new method is proposed to identify the high frequency signal from three low-ratio sampling spectra. The complicated case of vibration measurement ofrotary blades is investigated with error analysis and illustratrated by a numerical example.
