RÉSUMÉ

It is shown that the vast class of sonotrodes (tools, concentrators), used in technological plants for ultrasonic treatment of materials, allows systematiza-tion on the modal principle. The types of vibration (modes in sonotrodes) can be associated with characteristic segments of the frequency spectrum branches of a rectangle and a solid finite cylinder. Depending on the position of these segments in the spectrum, the sonotrode types are defined as low- or high-frequency. The resonance mode structure suggests division of the elements into three types - single mode sonotrodes, converters and multistage elements. An appropriate grading of sonotrodes is suggested in the paper. The principal stages of the sonotrode design and the required mathematical apparatus are considered.
