Проведено теоретическое исследование распространения бегущих продольных волн в кольцевом твёрдотельном акустическом резонаторе с бимодульной упругой нелинейностью и линейной диссипацией. На основе точного решения эволюционного уравнения получены аналитические выражения для формы, амплитуды, спектра, резонансной кривой и нелинейной добротности резонатора.

Nazarov V.E. and Kiyashko S.B.

We study theoretically the propagation of longitudinal traveling waves in a ring-shaped solid-state acoustic resonator, which is characterized by bimodular elastic nonlinearity and linear dissipation, under the conditions of harmonic resonant excitation. An exact solution of the evolution equation describing a self-similar periodic wave and its spectrum in an unbounded medium with bimodular nonlinearity and linear dissipation are used as a basis to obtain analytical expressions that define the waveform, amplitude, and spectrum of the traveling wave within the resonator, as well as the resonance curve and nonlinear Q-factor of the resonator.
