The motion law of a biharmonic oscillator modeling a mechanical structure with one degree of freedom with stepwise varying sti ness is considered. We have constructed dependences of the amplitudes of the harmonics of the signal on the relative change in sti ness on half-cycles of vibrations. The di erence in the orders of the smallness of the amplitudes of the even and odd harmonics is revealed in the Taylor expansion in terms of the parameter of the relative change in the sti ness. |
