Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic detection, in particular to a composite material ultrasonic detection auxiliary device. Background Art

[0002] Ultrasonic waves are mechanical waves with a frequency higher than 20 kHz. This type of mechanical wave can propagate in a material at a certain speed and direction. When it encounters a heterogeneous interface with different acoustic impedance (such as a defect or the bottom surface of the object being measured), it will be reflected.

[0003] When performing ultrasonic testing on composite materials, since composite materials have a variety of specifications, misalignment is prone to occur during the testing process, resulting in insufficient close contact between the ultrasonic testing equipment and the composite materials, affecting the normal use of the subsequent ultrasonic testing equipment and causing errors in the ultrasonic testing of composite materials. At the same time, the installation process of traditional ultrasonic testing equipment is relatively cumbersome, which slows down the speed of ultrasonic testing work. Utility Model Content
