Изобретение относитс к ультразвуковой технике и может быть использовано дл электрического возбуждени механических колебаний при ультразвуковой обработке материалов, в ультра- 5 звуковой сварке, дефектоскопии и т.п.The invention relates to an ultrasonic technique and can be used for the electrical excitation of mechanical vibrations in the ultrasonic processing of materials, in ultrasonic welding, flaw detection, etc.
Известны способы возбуждени акустических колебательных систем, используемых дл ультразвуковой микросварки , заключакндиес в подаче на ульт- 10 развуковой преобразователь электрического сигнала качающейс частоты l.Methods are known for driving acoustic oscillatory systems used for ultrasonic micro-welding, concluding for supplying an oscillating frequency electrical signal l to the ultrasonic transducer.
Недостатком данного способа вл етс нестабильность выходной мощности колебательной системы из-за воз- 15 можного выхода резонансной частоты за пределы качани частоты.The disadvantage of this method is the instability of the output power of the oscillatory system due to the possible output of the resonant frequency beyond the frequency sweep.
Наиболее близким по технической сущности к изобретению вл етс спо- 20 соб, включающий возбуждение колебательной системы высокочастотным электрическим колебанием на резонансной частоте, вьлделение сигнала обратной св зи и автоматическую подстройку 25 частоты 2.The closest in technical essence to the invention is a method including excitation of an oscillating system by high-frequency electric oscillation at a resonant frequency, the generation of a feedback signal and automatic tuning 25 of frequency 2.
Недостатки известного способа мала стабильность выходных механических параметров узкой полосы , в которой происходит подстройка частоты, и отсутствие стабилизации амплитуды колебаний.The disadvantages of this method is the low stability of the output mechanical parameters of a narrow band, in which the frequency adjustment occurs, and the lack of stabilization of the amplitude of oscillations.
Цель изобретени - повьшение стабильности выходных механических параметров колебательной cncTeNOj за счет расширени ее полосы пропускани .The purpose of the invention is to increase the stability of the output mechanical parameters of the vibrational cncTeNOj due to the expansion of its passband.
Это достигаетс тем, что по способу , включающему возбуждение колебательной системы высокочастотными электрическиг-ш колебани ми на резонансной частоте, колебательную систему одновременно возбуждают несколькими дополнительными низкочастотными электрическими колебани ми, имеющими отношение частот в виде натурального р да, при этом минимальна часто-, та fJ низкочастотных колебаний равна (1,2-1,5) Af .,«(2-2,5)Af, а амплитуды напр жений каждого последующего низкочастотного колебани св заны с амплитудой U/J на частоте f следующим соотношениемThis is achieved by the fact that, using a method involving exciting an oscillating system with high-frequency electrically oscillations at a resonant frequency, the oscillating system is simultaneously excited by several additional low-frequency electrical oscillations having a frequency ratio in the form of a natural series, with minimal frequency and fJ low-frequency oscillations equal to (1.2-1.5) Af., "(2-2.5) Af, and the amplitudes of the voltages of each subsequent low-frequency oscillations associated with the amplitude U / J at frequency f as follows: m
