Abstract
Изобретение относится к неразрушающему контролю физических характеристик материалов изделий и может быть использовано для измерения напряженного состояния различных материалов, испытывающих значительные нагрузки в процессе эксплуатации. Предлагаемое экспериментальное устройство, отличающееся простотой конструкции, позволяет находить с высокой точностью механические напряжения в исследуемом материале. Достигается это тем, что установка для определения механических напряжений в конструкционных материалах, содержащая корпус, заполненный иммерсионной жидкостью, акустическое фокусирующее устройство в виде линзы, взаимодействующее с ультразвуковым преобразователем, и блок приема информации с регистрирующими датчиками, причем внутри корпуса, на противоположной стороне от блока приема информации, расположены элементы крепления в виде пресса исследуемого образца с возможностью создания в нем механических напряжений, а в торце исследуемого образца установлен ультразвуковой преобразователь с возможностью пропускания ультразвуковых колебаний вдоль исследуемого образца, на котором установлен сферический элемент в направлении фокусирующего устройства, сверху на корпусе установлена съемная крышка, на которой с внутренней стороны расположены регулируемые акустические вогнутые линзы, при этом блок приема информации снабжен конусом, закрепленным на крышке корпуса, с возможностью перемещения и регулирования расстояния между регистрирующими датчиками. Регистрирующие датчики блока приема информации подпружинены со стороны боковых поверхностей блока, а сам блок выполнен с возможностьюThe invention relates to non-destructive testing of the physical characteristics of materials of products and can be used to measure the stress state of various materials experiencing significant loads during operation. The proposed experimental device, which is distinguished by its simplicity of construction, allows one to find mechanical stresses in the material under investigation with high accuracy. This is achieved by the fact that the installation for determining mechanical stresses in structural materials, comprising a housing filled with an immersion liquid, an acoustic focusing device in the form of a lens, interacting with an ultrasonic transducer, and an information receiving unit with recording sensors, and inside the housing, on the opposite side receiving information, there are the fastening elements in the form of a press of the sample under study with the possibility of creating mechanical stresses in it, and in the end face we investigate A sample of ultrasound transducer is installed with the possibility of transmitting ultrasonic vibrations along the sample under study, on which a spherical element is mounted in the direction of the focusing device, a removable cover is installed on the top of the housing, on which inner side there are adjustable acoustic concave lenses, mounted on the housing cover, with the ability to move and adjust the distance between the recording sensors. The recording sensors of the information receiving unit are spring-loaded from the side surfaces of the block, and the block itself is configured to
