Description
  • This work is concerned with suppression of nonlinear effects in piston-driven acoustic resonators by means of two-frequency driving technique. An iterative adaptive algorithm is proposed to calculate parameters of the driving signal in order that amplitude of the second harmonics of the acoustic pressure is minimized. Functionality of the algorithm is verified firstly by means of numerical model and secondly, it is used in real computer-controlled experiment. The numerical and experimental results show that the proposed algorithm can be successfully used for generation of high-amplitude shock-free acoustic field in resonators.

  • Práce se zabývá problematikou potlačování nelineárních jevů v rezonátorech buzených pístem současně na dvou kmitočtech. V jejím rámci je navržen adaptivní iterační algoritmus pro výpočet parametrů budicího signálu potlačujícího druhou harmonickou zvukového pole. Navržená metoda je ověřena jednak numerickou simulací a dále pomocí počítačem řízeného experimentu. Numerické a experimentální výsledky potvrzují funkčnost navrženého algoritmu a jeho použitelnost pro generování intenzivních zvukových polí. (cs)
