Ultrasonic transmission method for testing curved composite parts

Abstract: In this paper, the detection of common defects such as inclusion, delamination for curved composite materials is studied. The principle of measuring porosity is focused on introducing. The technology of trajectory planning and motion control for twin-robot system of testing various curved composite parts using ultrasonic transmission method is also discussed. An ultrasonic NDT system is developed for testing large-scaled curved composite components used in aerospace and other fields. With many advantages, it w… Show more

“…When the acoustic wave is reflected, scattered, and transmitted at different interfaces within the object, the echo signal is received again through the probe. We can detect the position and size of micro defects in the object by comparing and analyzing both the time domain and frequency domain of a single point and the whole process echo signal carried out through the signal processing system [19]. Hoh et al [20] used the MP and CP4 ultrasonic probes of 230 MHz to scan the same flip chip and obtained two ultrasonic images of the chip, and the chip defects are detected by image processing in a complementary way.…”

“…Çalışmada yörünge planlama ve hareket kontrolü teknolojilerine sahip ikiz robotlar kullanılmıştır. Sonuç olarak çalışmalarında, UT yönteminin, kusur algılama işlemindeki doğruluk ve verimlilik gibi parametreleri iyileştirdiği belirlenmiştir [9]. Rostami Mojtaba ve arkadaşları, MKA yöntemini kullanarak kusurların genişliğini tespit edebilmek için yeni bir yaklaşım sunmuşlardır.…”
