Abstract: A method for generation of acoustic vibrations based on shock excitation of a magnetostriction transducer by a pulse electrical signal. The electrical signal is generated in the form of unidirectional half-cycles of cosinusoidal voltage, with a duration from one to two half-cycles of acoustic vibrations produced by the loaded tansducer. The repetition frequency of the electrical pulses is taken to be equal to, or multiple of the frequency of acoustic vibrations.A source of acoustic vibrations comprises a power unit (7), a pulse repetition frequency control unit (10) and a reservoir capacitor (6), the plates whereof are connected through a power circuit of a switching element (5) to a field winding (2) of the magnetostriction transducer (1). The source also comprises an auxiliary field winding (3) disposed on the same magnetostriction transducer (1) and connected by the aiding connection method to the winding (2); an auxiliary switching element (8); and a switching element control unit (9). The auxiliary winding (3) is connected to the plates of the capacitor (6) through a power circuit of the switching element (8) and through the power unit (7), and an output of the pulse repetition frequency control unit (10) is connected to an input of the switching element control unit (9), the outputs whereof are connected to control circuits of the switching elements (5 and 8), respectively.The source of acoustic vibrations is designed primarily for ultrasonic descaling of heat-exchange apparatus.
