Method for determination of parameters of non-linear dissipative oscillatory system by which one forms two modes of non-stationary forced vibrations of non-linear dissipative oscillatory system, in first mode frequency of signal of forced effect one changes with first constant rate, in second mode – with second constant rate, in each mode one sets initial and end value of amplitude of forced vibrations of non-linear dissipative oscillatory system, and in first mode one sets first initial and first end valuesof amplitude of forced vibrations, one measures, fixes and registers first time intervaland numberof cycles of forced vibrations in that time interval at change of frequency of signal of forced effect with first constant rate, with measurement, fixation and registration of second time intervaland numberof cycles of forced vibrations in that time interval at change of frequency of signals of forced effect with second constant rate(or) at change of amplitude of oscillations of non-linear oscillatory system in end mode from its initial value to end value, and in first mode from first initial value to first end value, at that one additionally forms the third and fourth modes of non-stationary forced oscillations of non-linear dissipative oscillatory system. |
