Изобретение относится к указателям нагрузки различных элементов, в частности элементов соединения, таких, как болты, заклепки, штифты и т.п., и может быть использовано совместно с ультразвуковым преобразователем. Сущность: изобретение раскрывает конструкцию ультразвукового указателя нагрузки и способ его изготовления. Ультразвуковой указатель нагрузки представляет собой деформируемую под нагрузкой деталь, на одной из поверхностей которой, являющейся одним из электродов, расположен ультразвуковой преобразователь. Между двумя электродами размещена акустоэлектрическая пленка, которая должна быть выращена на первом или на втором электроде различными методами, например, методом осаждения из газовой фазы, методом магнетронного распыления и т. д. Материал и габариты акустоэлектрической пленки и второго электрода могут быть различными. Это отражено в различных вариантах исполнения. В указателе нагрузки может быть выполнена дополнительная поверхность, имеющая свойство отражения ультразвуковых волн обратно к преобразователю. Указатель нагрузки может быть снабжен электронным управляющем устройством, устройством отслеживания электронных сигналов, а также устройством приложения к детали крутящего момента. Способ изготовления ультразвукового указателя нагрузки определяет метод получения акустоэлектрической пленки на одном из электродов и изготовления деформируемой под нагрузкой детали.The invention relates to load indicators of various elements, in particular connection elements, such as bolts, rivets, pins, etc., and can be used in conjunction with an ultrasonic transducer. SUBSTANCE: invention discloses a design of an ultrasonic load indicator and a method for its manufacture. An ultrasonic load indicator is a component deformable under load, on one of the surfaces of which, which is one of the electrodes, is an ultrasonic transducer. An acoustoelectric film is placed between two electrodes, which must be grown on the first or second electrode by various methods, for example, by gas phase deposition, magnetron sputtering, etc. The material and dimensions of the acoustoelectric film and the second electrode can be different. This is reflected in various designs. An additional surface having the property of reflection of ultrasonic waves back to the transducer can be made in the load indicator. The load indicator can be equipped with an electronic control device, a device for monitoring electronic signals, as well as a device for applying torque to a part. A method of manufacturing an ultrasonic load indicator determines the method of producing an acoustoelectric film on one of the electrodes and manufacturing a workpiece deformed under load.
