Uwagi o hipotezie małej nieliniowości drgań konstrukcji płatowców

Experimental investigation of frequency of resonanse vibrations as a function of harmonic excitation force value (or of the amplitude of vibration) reveals characteristic non-linearities in the low range of the amplitude of vibration. Analysis of the non-linearities in question enabled the scope of application of the theory of small non-linearity of vibration of aircraft structure to beocme more precise.
