RT Journal Article ID 06ae387775922116 A1 Krasnoshapka, Vladimir A. T1 Self-Oscillating Modes in Controlled Machine Aggregates JF Journal of Automation and Information Sciences JO JAI(S) YR 2005 FD 2005-02-01 VO 37 IS 1 SP 24 OP 28 AB We investigate excitation of biharmonic oscillations in controlled machine aggregates on the basis of the mathematical model, which takes into account interaction of fields of different physical nature. It was ascertained that on investigation of biharmonic self-oscillations it is necessary to take into account character of frequency spectrum (equidistant, unequally spaced), which stipulates distinction of the system of equations for determination of amplitudes of biharmonic self-oscillations and investigation of their stability.
