Method for determination of parameters of non-linear dissipative oscillatory system includes formation of two modes of forced oscillations. In each of modes one sets initial and end value of amplitudes of forced oscillations on non-linear dissipative oscillatory system with measurement of values of first and second time intervalst,t and number of cycles (periods) n, nof oscillations in those time intervals, respectively, with change of frequency of signal of forced effect at change of amplitude of forced oscillations in each time interval from initial to end value in first mode with first constant velocity V, and in second mode – with second constant velocity V, with fixation of values of average frequenciesin first and second mode, respectively of the first and second ranges of frequencies at change of amplitude of forced oscillations from initial value Xto end value XOne sets in first and second modes of forced vibrations the first initial and first end X, X, second initial and second end X, Xvalue of amplitudes of forced oscillations of non-linear dissipative oscillatory system, respectively. One changes inertia of non-linear dissipative oscillatory system with performing the above set of operations on determination of the thirdt and fourtht time intervals and numbers of cycles n, nof oscillations in those time intervals. |
