Lucrarea prezintă analiza numerică a unui traductor piezoelectric de ultrasunet destinat aplicațiilor biologice de microcavitație. Se analizează numeric sursa de ultrasunet în variantă bidimensională, simplificată, cu simetrie axială. Se determină frecvențele naturale, modurile proprii ale deformării asociate acestor frecvențe naturale, respectiv frecvența de rezonanță. Pentru studiul în regim dinamic se consideră alimentarea straturilor piezoceramice la o tensiune sinusoidală la frecvența de rezonanță determinată anterior.Referințe
