Description
Изобретение относ тс к электронной технике и может быть использовано, в частности, в качестве высокостабильных источников питани в прецизионных установках дл ультразвуковой обработки материалов.The invention relates to electronic engineering and can be used, in particular, as highly stable power sources in precision installations for the ultrasonic processing of materials.
Известен пьезоэлектрический преобразователь , содержащий переходной слой, рабочий и согласующий пьезоэлементы и демпфер, при этом дл регулировани формы АЧХ механических колебаний вспомогательный пьезоэлемент шунтирован параллельно соединенными индуктивностью и активным резистором 11 A piezoelectric transducer is known, which contains a transition layer, a working and matching piezoelectric elements and a damper, while for adjusting the shape of the frequency response of mechanical oscillations, the auxiliary piezoelectric element is shunted in parallel by inductance and an active resistor 11
Недостатком устройства вл етс мала степень регулировани формы АЧХ сложной ультразвуковой колебательной системы УЗКС , состо щей из пьезокерамических преобразователей , пассивной накладки и активной накладки, включающей переходной стержень, концентратор и деформирующий инструмент, большой эквивалентно колеблющейс массы активной накладки.The drawback of the device is a small degree of regulation of the shape of the frequency response of a complex ultrasonic vibrating system of the ultrasonic vibrating system, consisting of piezoceramic transducers, a passive lining and an active lining, including a transition rod, a concentrator and a deforming tool, large equivalent to the oscillating mass of the active lining.
Известно ультразвуковое излучгиощее устройство, содержащее пьезопреобразователь , регулируемую индуктив ,ность, генератор электри 1еского напр жени , управл ющий каскад, трансформатор тока и блок эталонного на- , пр жени . Это устройство имеет расширенный диапазон частот, в пределах которого обеспечиваютс ультразвуковые колебани посто нной амплитуды за счет регулировани величины электрического напр жени генератора . При этом в качес- е пара10 метра, по которому косвенно суд т о величине механических колебаний, выступает электрический ток 2.An ultrasonic radiation device is known, which contains a piezoelectric transducer, an adjustable inductance, a generator of electrical voltage, a control stage, a current transformer, and a reference voltage unit. This device has an extended frequency range within which constant amplitude ultrasonic oscillations are provided by adjusting the magnitude of the electrical voltage of the generator. In this case, as a parameter, by which indirectly the magnitude of mechanical oscillations is judged, an electric current 2 acts.
Однако дл сложных ультразвуковых колебательных систем (преобра15 зователь, согласующий элемент, концентратор и деформирукнций инструмент ) строгого соответстви между АЧХ потребл емого тока и АЧХ механических колебаний концентратора However, for complex ultrasonic oscillatory systems (converter, matching element, concentrator, and tool deformations) a strict correspondence between the frequency response of the current consumed and the frequency response of the mechanical oscillations of the concentrator
20 ( инструмента) не существует. В св зи с этим эффективность частотной настройки потребл емого тока существенно снижаетс .20 (tool) does not exist. In this connection, the efficiency of the frequency tuning of the consumed current decreases significantly.
