Determining the parameters of a self-vibratory system from an analysis of its forced vibrations
Copyright policy )Determining the parameters of a self-vibratory system from an analysis of its forced vibrations
The response of a Van der Pol self-vibratory system to harmonic excitation is characterized by periodic and quasiperiodic vibrations in a specific relation. Pericdic vibration modes occur when the source of companion vibrations is shut-down. The information contained in the amplitude-phase-frequency characteristic of the fundamental mode, whose frequency is equal to the external excitation frequency, suffices for determining the parameters of the nonconservative force by the method proposed here.
