Automated System for Ultrasonic Non-Contact Non-Destructive Quality Control of Composite Products With Complex-Shape Surface

The article describes a universal automated system for ultrasonic non-contact testing of complex-profile products made of composite materials, developed and put into commercial operation. Experimental studies and results of industrial operation have clearly shown that the developed automated control system and information processing algorithm provide the specified reliability of identifying defects in products, while the following is carried out: automatic adaptation of the control system to products with an arbitrary surface shape by adjusting it according to a 3D model of the product embedded in the control system, which allows you to significantly expand the range of controlled products without significant modification of the control system; increasing noise immunity and detecting defects using adaptive algorithms with a given error using special signal processing algorithms; automatic control of products with complex surface shapes with changing control modes; automated registration of detected defects on the surface of the controlled product.
