Název v původním jazyce

Nonlinear acoustic fields in two mechanically coupled resonators

Popis výsledku v původním jazyce

The paper deals with a description of nonlinear standing waves in cylindrical resonators which are separated by an elastically mounted wall. The wall represents a quasi-harmonically driven oscillator which connects nonlinear acoustic fields in the resonators. For the description of the nonlinear acoustic fields were derived model equations. The model equations are represented by the inhomogenenous Burgers equations. These two model equations are supplemented by an oscillator motion equation. The assumedresonant system contains many optional parameters which enable to investigate a number of interesting configurations of parametrically excited nonlinear acoustic fields. The system of model equation was numerically solved both the time and frequency domain. Some of the assumed configurations were solved analytically for the case of steady acoustic fields. Thanks to many optional parameters the investigated resonant system is relatively complex and enables to study a number of interestin
